Yes, but we are not exactly there yet: https://arewemodulesyet.org/

Edit: Saw after posting this was already posted in a top level comment.

Modules are a massively over engineered "solution" to the problem that require significant refactoring to actually make use of them. Have you tried to properly use modules (i.e. create ones in your software, not just import std)? It's super clunky and still hardly usable.

I doubt we'll see Unreal Engine get any benefit from that in a long time for example. It could be so much better, working fully automatically with almost all existing code so long as you use IWYU, which is already standard for large projects where this is needed the most.
