Projects in active maintainance are mostly migrating to C++11 already.
They don't care about this. But there is a huge existing code base that
doesn't specify -std=XXX and for which bad things can happen. Compile
errors are on the more harmless side of things.

Pointing to GCC doesn't really change anything. They don't maintain
those code bases either.
