A single package prevents different versions of -user and -system (at
least in a nice way).
Sometimes the latest version of qemu doesn't play nice with some kernel
versions because of newer OpenBIOS/other BIOSes versions breaking with
newer kernels - it's a common scenario for non-x86/x86_64.
And there may be some particular need for -user to be a newer or
different version than system, though i can't come up with any idea of why.
At the moment i don't think -user is useful for anything in particular
because of the limitations you wrote.
Problem is building two different versions in a single package wouldn't
be all that great, for all intents and purposes they would be two
packages anyway.
