No, only a small amount of people care about compiler benchmarks... which are not representative of general-purpose code anyway since they seem more interested in testing vectorisation and other dubious features that are only important for a tiny subset of everything a compiler gets used for. That said, ICC and MSVC can achieve similar or better results without going insane with UB, so it's clearly not as strictly necessary as the lame pedants want you to believe.
