It would make sense in it being the second release with full c++17 support, so
we could expect the support to be mature in gcc 8. I am a little sceptical
personally though, because I just recently got burned by a C++17 change, where
a number of uses of functor classes broke because pointers to functions with
noexcept is now a separate type. So code that worked with C++14 is now illegal
in C++17 and requires doubling the number of specialized functor templates,
and still isn't fully source compatible with C++14 (though all nice clean code
will be compatible)
