This is ignoring that LLVM is first and before all designed as reusable libraries. Bumping requirements is causing other problems than just being able to build with the just built compiler: namely deployment and integration in other products. For example, you may be forced to isolate components in dynamic library that talks with each others through C APIs and each statically link the C++ standard library. It can become fairly complicated when this does not fit your setup and you get forced into this because LLVM decided to bump their standard.
