The problem is that one might want to use libstdc++ (GCC) and libc++ (LLVM) along with GCC ABI and LLVM ABI, respectively. Fedora currently enables the GCC case, but one has to fall back to GCC ABI even when using an LLVM library.

Providing a useful development environment for libc++ is a lot of work. We would have to compile most C++ libraries twice, so that they can be used with either C++ standard library, and provide tooling to prevent accidental cross-linking reliably. I really do not see the benefit for the developer. More choice isn't always an improvement.

Thanks,
Florian
