The dependencies we express in kconfig are already pretty complicated, 
and that is continuously causing problems.

Stuffing more stuff into kconfig for such an exotic developer-only use

And as already said, tomorrow someone might want to boot an allyesconfig 
kernel on a Pentium-MMX...

allyesconfig is not random.
