This is due to `-std:c++20` implying `/permissive-` which implies `/Zc:twoPhase-`. We could therefore just disable it based on language version alone, not just based on whether we are using modules.
I previously tried to make it the default everywhere in https://reviews.llvm.org/D103772. @rnk argued we could always make it the default. Given that MSVC is essentially phasing it out and making all their headers compatible with `/Zc:twoPhase-` for the sake of C++20 support, it should be more feasible than previously.
