I don't really have any opinions on the matter; I don't really use
defconfigs in any of my workflows. So, I just want whatever is easier
for people. The thing that makes the most sense to me would be to
provide a "merge-kunitconfig" option similar to what kselftest does,
but I don't intend on doing that in the initial patchset, unless
someone really thinks that I should do it. So in the meantime, I guess
provide both since that gives people options?

In anycase, I just (finally) sent out v4, so I suggest we continue the
discussion over there.
