You couldn't imagine the number of complaints I got from users about dropping
kqemu. It caused me considerable pain. Complaints ranged from down right
hostile (I had to involve the Launchpad admins at one point because of a
particular user) to entirely sympathetic.
kqemu wasn't just a maintenance burden, it was preventing large guest memory
support in KVM guests. There was no simple way around it without breaking kqemu
ABI and making significant changes to the kqemu module.
Dropping features is only something that should be approached lightly and
certainly not something that should be done just because you don't like a
particular bit of code.
