An RFC is definitely helpful for discussion, though reproducing it on
real hardware is always ideal.
Speaking of which, it reminds me of a DRM patch I sent earlier—which
also deals with register state
restoration across power cycles.
It was a real bug that had existed for over 10 years, fully tested and
verified on hardware,
yet it hasn't been merged yet.
