Honestly I dont find the qemu code base that bad, or at least not really much worse than any other C codebase of similar age + size. What I find worst about it is really the lack of documentation on the various subsystems. Once you kinda figure them out its not so bad.

Also these "extra works" might simplify the development in the later stage when deeper customization is needed (especially when you consider the possibility of mainlining the work).

I feel like once you have implemented a device emulation framework, you have basically just re-invented qemu. Also that's quite alot of stuff to implement, that I'm not particularly interested in. At the moment I don't really have any code that couldn't be unstreamed into qemu, however the general plan is to keep it in a form that's reasonably maintainable as a patch on qemu

I'm definitely open to cooperation, but I'm not sure how much overlap there really is among the various projects. Although having a shared frontend to qemu more tailored to calculators would be useful.
