Yeah, and even then, such a change would be quite disruptive for users; they would need to hard upgrade every package that uses libc++ in one step, otherwise they'd have broken executables all around.

So I think keeping backwards compat symbols around for at least a major version or two, would be valuable in any case.

(I haven't yet studied what the impact on the referenced symbols is from this change, for something like clang/llvm built on top of libc++ on mingw.)
