Concept template parameters were introduced in C++26 by [P2841R7](https://wg21.link/P2841R7) [3]. We propose to extend this feature with partially applied concepts. This feature was introduced in [P2841R0](https://wg21.link/P2841R0) [1] and removed in R1 to reduce the scope of the initial paper, and because [EWG initially found](https://github.com/cplusplus/papers/issues/1546#issuecomment-1587401642) [this part of the feature less compelling](https://github.com/cplusplus/papers/issues/1546#issuecomment-1587401642).
