I fear that will render my qom-test useless, which is supposed to test
our defaults. If -nodefaults drops serial ports, floppy drives, etc.
that will reduce its usefulness. Unless of course we find a way to
override -nodefaults with some generic -defaults options. :)
I haven't noticed anyone actually adding qtests along with new machines,
adding them to qom-test already required some poking of mine.

End of last year I was preparing some qtests for optional PCI devices,
but even such stubs are hard to share across multiple shoulders due to
resulting Makefile conflicts...
