If we can do that, it's naturally preferable. Let's see how it goes.

Sorry, didn't mean to misrepresent. I should have said that it is one way of implementing `obarray-make` if compatibility with vector-assuming code really is a serious concern.

I'm all for it but those obarray functions weren't mentioned in NEWS at the time nor in the manual (which even today recommends, even mandates, use of make-vector) so perhaps we need a bridge?
