We can say that all we like, but the reality is 'we ship it, we support it'. Users are going to file bugs if things break & are going to want them fixed In RHEL we ship Xen with SDL support for framebuffer, even though our tools only 'support' VNC. We still have multiple bugs file against SDL and we have to fix them. Users don't distinguish, they just use all the features you provide them and expect them all to work. > Nevertheless being able to pass random additional arguments to $emulator > is required for any serious development work.

Historically we've not had very complete coverage of QEMU args, but we've been adding alot of new functionality recently so the need for extra args is reducing all the time. We recently added serial, parallel, sound and drive support. USB is the next on the list at which point we basically have coverage of all the important options we should reasonably expect. Creating wrapper scripts for experimentation is not that difficult.
