Was about to express the same concern: Who will test that those
preintegrations still work, produce reasonable results? If people stand
up and say, "hey, I'm doing that anyway already, will take care of
this!", then this could work.

And then the next aspect would be how to make generic assets like kernel
configurations and integration reusable for xenomai-images, and vice versa.
