Well, it depends what you define as our core target :-)
I think we get quite a lot of users that want some useful ability
to see what their guest code is doing, and these days (when
dev board hardware is often very cheap and easily available)
I think that's a lot of the value that emulation can bring to
the table. Obviously we would want to try to do it in a way
that is low-runtime-overhead and is easy to get right for
people adding/maintaining cpu target frontend code...
