I was thinking mostly of architecture-independent options, i.e.
the stuff that is in lib/Kconfig.debug but isn't too expensive
to be run in a regular test environment. Enabling those
for a build/boot automation environment would be particularly
useful as you'd catch more bugs that get introduced through
a random patch.

It would certainly need buy-in from distro maintainers. I've discussed
this with Laura Abbott in the past, and she was interested in
principle.
