I've long been surprised there isn't more multiversion stuff built right into every language compiler; I would have thought Intel would be very motivated to get more binaries lighting up the features they add to their expensive top line CPUs.
But yeah no, on the whole cost of the checks and duplicated binary size aren't seen as worth it, so instead it's piecemeal implementations mostly in numeric packages like eigen and lapack.
