1. A turbomachine component, comprising: a turbine blade, which is rotatable about a rotor of a turbine for power generation operations; anda platform with which the turbine blade is to be assembled,the turbine blade being formed to define a main circuit having a circumferential appendage formed with radial tapering or curvature and extending circumferentially from the main circuit and the platform being formed to define:a platform circuit, anda substantially radially extendible pathway configured to be coupled to the appendage and to the platform circuit,wherein the appendage comprises a radially outward side, which is configured to be disposed proximate to the platform circuit, and which is configured with shallow tapering or curvature and a radially inward side, which is distant from the platform circuit, and which is configured with deep tapering or curvature, the deep tapering or curvature of the radially inward side being deeper than the shallow tapering or curvature of the radially outwardly side. 2. The turbomachine component according to claim 1, wherein the pathway is extendible substantially radially outwardly from an end of the appendage to the platform circuit. 3. The turbomachine component according to claim 1, wherein the radial tapering or curvature is distant from the platform circuit. 4. The turbomachine component according to claim 1, wherein an intersection of the pathway and the platform circuit comprises rounded edges. 5. A turbomachine component, comprising: a turbine blade, which is rotatable about a rotor of a turbine for power generation operations;a platform with which the turbine blade is to be assembled, the turbine blade being formed to define a main circuit having a circumferential appendage and the platform being formed to define a platform circuit and a substantially radially extendible pathway configured to be coupled to the appendage and to the platform circuit; anda plug to prevent leakage from a radially inward section of the pathway, an entirety of the plug being disposed radially inwardly from a radially inward-most portion of the pathway. 6. The turbomachine component according to claim 5, wherein the plug is one or more of welded, brazed or mechanically fastened proximate to the platform. 7. A turbomachine component, comprising: a turbine blade, including an airfoil and a root, which is rotatable about a rotor of a turbine for power generation operations; anda platform with which the root of the turbine blade is to be assembled,at least the airfoil of the turbine blade being formed to define a main circuit having a plurality of cavities and a circumferentially extending and radially tapered or curved appendage comprising radially inward and outward sides of which only the radially inward side has tapering or curvature relative to an axial dimension of the turbomachine component,the platform being formed to define a platform circuit and a substantially radially extendible pathway configured to be coupled to an end of the appendage and any one or more of the plurality of the cavities of the platform circuit. 8. A method of connecting circuits of a turbomachine component, comprising: casting a turbine blade, which is rotatable about a rotor of a turbine for power generation operations, such that the turbine blade defines a main circuit having an appendage;casting a platform with which the turbine blade is to be assembled such that the platform defines a platform circuit; andfollowing the casting of the turbine blade and the platform, machining a substantially radially extendible pathway into the casted platform such that the machined pathway is configured to connect the main circuit and the platform circuit when the casted turbine blade is assembled with the casted platform. 9. The method according to claim 8, further comprising assembling the casted turbine blade with the casted platform, wherein the machining of the pathway is conducted prior to or subsequent to the assembling. 10. The method according to claim 8, wherein the casting of the turbine blade comprises casting the turbine blade such that the appendage extends circumferentially from the main circuit and is formed with radial tapering or curvature. 11. The method according to claim 10, wherein the machining of the pathway comprises machining the pathway to be extendible substantially radially outwardly from an end of the appendage to the platform circuit. 12. The method according to claim 10, wherein the casting of the turbine blade comprises casting the turbine blade such that the radial tapering or curvature is distant from the platform circuit. 13. The method according to claim 8, wherein the machining of the pathway comprises machining rounded edges at an intersection of the pathway and the platform circuit. 14. A method of connecting circuits of a turbomachine component, comprising: forming a turbine blade, which is rotatable about a rotor of a turbine for power generation operations, such that the turbine blade defines a main circuit having an appendage;forming a platform with which the turbine blade is to be assembled such that the platform defines a platform circuit;following the forming of the turbine blade and the platform, forming a substantially radially extendible pathway in the platform such that the pathway is configured to connect the main circuit and the platform circuit when the turbine blade is assembled with the platform; andplugging the pathway. 15. The method according to claim 14, wherein the plugging comprises one or more of welding, brazing or mechanical fastening of a plug proximate to the platform.
