Last time I checked, outside most C++ compilers were still catching up with C++11.
There are more C++ compilers out there than just clang and gcc. Even those aren't 100% compliant at library level, if I am not mistaken.
Still quite a few rows with N.

I was only wrong about clang.
So my point still holds for gcc, and it doesn't change the fact, that there are more compilers out there than the triad clang, gcc, vc++.
