I thought we agreed to remove the workaround that we had for this and just declare that the old MSVC STL release was buggy and users should update:
https://bugs.llvm.org/show_bug.cgi?id=42027
It's a point release that preserves ABI compatibility, so there's less motivation for us to add a compat hack.

In general, we should seriously think about sunsetting some MS compat hacks that aren't needed for new SDK/STL versions to save on clang maintenance costs. The complexity they add is surprisingly expensive. For example, -fdelayed-template-parsing is a recurring source of compat issues in clang-tools-extra (see the commit logs), and I would like to revive D66394 <https://reviews.llvm.org/D66394> to get it disabled by default soon.
