I meant across unittests, we should be consistent. All unittests do
either "depends on KUNIT" or "select KUNIT". The question I would ask
is does KUNIT need to be user visible or is useful to enable without
any unittests enabled? With depends, a user has 2 options to go enable
vs. 1 with select.
But if you want a global kill switch to turn off all unittests, then
depends works better.

You'll be so happy that 100s of tests have been created using kunit,
it won't be a big deal. :)
In any case, I wouldn't spend more time on this.
