I'm not so sure. It's pretty low on my list of priorities. Most users only need
one target, speed of execution and/or features is likely much more important
for them,
and these refactorings make code more generic and harder to extend.s
We ought to have a set of device models that are compiled once, with
well defined interfaces that model the actual way the various buses
communicate. This should all roll into a generic CPU API. Then we
should have a set of CPU implementations with choices including various
TCG targets and KVM targets.
You can still compile out TCG targets that you don't care about but the
key point is to get all of these interfaces correct.
This refactoring effort isn't really paying attention to improving
interfaces which I think is a bit problematic.
