What early adopters are using them? Because my impression is the tooling still isn’t there

People using Visual C++ with MSBuild, or clang with CMake and ninja.

CMake says they are there. Other tools mostly are not.

Nobody has said they are using them in anything important, but hopefully that is coming.

		CMake has support for named modules but does not support header units or C++23 module features such as import std;
