Note it is not a free for all. The rawhide guidelines indicate that FESCO
approves the shipping of beta/rc releases for low level components[1].
The pre-release packages are still expected to be of high enough quality
that they are usable in the normal way.

If anything I'd say that kernel is already not in compliance with the
rawhide guidelines. The combination of the large number of debug options
enabled has gradually slowed the kernel down enough, that it is no longer
usable for some use cases. We don't want to extend this slowdown still
further

Rawhide is somewhere to get integrated testing of software setup /
combinations we are expecting to ship in the next release. It shouldn't
be used to run experiments where we don't have confidence in our intent
to ship the result.

With regards,
Daniel
