Although backwards compliance is touted as a feature, it can be a horrible curse.
Good point.
I haven't checked, but I bet current Pentiums still implement the SAHF and LAHF instructions. I believe these were implemented in the Intel8088 to make it easier to port existing 8080 and Z80 software 30 years ago. If they haven't already been dropped, they should be. Any OS that's inclined to support them could implement an exception handler.
