"but just testing the most common hardware interfaces would surely save a lot of time"

But that's the stuff that gets tested anyway, by people. The trouble _is_ with the esoteric hardware.

Yes, so it is wasting the time of those people who have to painstakingly compile -rc kernels, load them and check that everything works. Not to speak about performance regressions in the drivers and filesystems, which I imagine must be hard to find and boring work. While a test suite publicly available might be run privately and also on the public git repos after every push. It is called continuous deployment, we do it at my company and it is fun, challenging stuff!

Testing RC kernels is not that hard. On openSUSE I just added the Kernel_HEAD repo and new kernels are installed with the other package updates. If a kernel breaks my system I can still just boot the old one and report the bug.
