Ok, sure - I applied such a rename on top.

(My intent was that since we run this for any case with `"_WIN32" in compilerMacros()`, it should be more generic, and we could branch out msvc specific detection here as well. But you're right that we can add a separate `or _msvcSupportsModules()`, in that case, which probably keeps the code easier to understand.)
