It could well be less annoying than having your guest be slow every day
because qemu masked CPU features that guest needs to be fast.

At least with a CPU upgrade, casual user can easily disagnose the
problem: the system was changed. If qemu is slow by default, there's no
way to find out why without reading the manual.  And we don't have one
:)
