It's hard to imagine a circumstance under which the r0 logs could be
relevant to anyone, since no user created r0. And the behavior
proposed above is... Well, let's just say I had to read it three times
myself, and I was already thinking hard about the issue :-). Do you
really want to have to document that behavior for users?

(IOW, I'm punting on the question of interface compatibility, because
even if this were compatible, I don't think we'd want to do it.)

I think r1 is a good default for almost all cases. In the rare times
when it's not, we can notice the problem, and handle the special case.
