:)
Regarding QEMU, the only thing I can thing of (and this is a stretch)
is USB legacy support. In other words, being able to drop PS2
keyboard/mouse for USB, but still supporting legacy software via SMM.
This doesn't seem worth the effort by a long shot.
Another take on removing PS2 sounds more interesting to me: a
legacy-free PC qemu hardware skew, with a legacy-free firmware (OVMF
:) and only supporting legacy-free compatible OS's.
