Depends on what you want to do, but in the common case yes. So we have
already moved in the wrong direction. Not a good reason to do more of
it.
Actually, I think changing the defaults to -m 1G and -machine
accel=kvm:tcg would be much less problematic than -M q35, so maybe that
should be our first step towards better defaults. (Or at least something
to schedule for 3.0.)
And even changing the default to -M q35, however problematic, would
still be nicer than making -M non-optional.
