I'm all for a Clang++ compatible with MSVC++. I'll love to replace
MSVC++ with Clang++ as my Windows compiler. That's not what arguing

I'm saying that anything that could suggest that MSVC++ is more
desirable than the other compilers is not only unfair, but would go
against Clang's interest because Clang will sooner get full MinGW
drop-in capability than MSVC++ drop-in capability. So any detriment to
the technical merits of MinGW would affect Clang too for a long time.
Naming APIs on a way that privileges MSVC++ hurts MinGW and Clang.
