A key component of CUDA is that the kernels are written in C/C++ and not some shader language you would only be familiar with if you were into graphics.

  CUDA C++ is not exactly standard either.

    It probably extends the language less than g++ or msvc do out of the box.

    Nowadays one can write pretty standard C++20 (minus modules), alongside CUDA frameworks that hide the non standard stuff on their internals.

  I mean it's technically c/c++ but the runtime is so different it might as well be a completely different ecosystem. Also, there's enough tooling popping up around the concept of avoiding using this ecosystem that it's pretty clear people want more than that.

  A key component of CUDA is that kernels can be written in C, C++, Fortran, and any language with PTX compiler backends. The fact many think CUDA is C/C++, is already the first error trying to replace it.
