The C++ standard is meant to harmonize the meaning of C++ code, it should when possible be portable, good for all operating systems, not just one.

And this is very much specific to a singular operating system, thus would harm its goals.

You can add it as a Windows specific extension, like a third-party library, but should not be part of the standard.

It wouldn't harm anyone if it was in C++, also generally it would make sense to complete std::print by adding wide string support.
