They haven't had time to accumulate patches that were useful five years ago but now just make things pointlessly slightly different. Similarly, you can generally assume that if someone has clang then it will be a relatively recent version of clang, because of how fast clang moved from not being practically usable to being very good. In a few years I assume that all of the various annoyances around targeting GCC on Linux will also apply to clang.
