otoh it's a bit sad to break allyesconfig kernels - there is
regression-testing value in being able to run such kernels.

I wonder if we can add a new boot option `allyesconfig-test' or

flag and take suitable avoiding action.

Or we could do it at compile-time - define
CONFIG_ALLYESCONFIG_TESTING in some fashion.
