I think the latter. And that makes sense to me. Push falls back to fetch
at runtime. And you never set a push url, so that's what happens.

But it is not symmetric. We do not fall back fetch to push. We _could_,
but that is a separate issue (one for git-fetch, and not git-remote).
And I do not think it is one anybody is particularly asking for.

We could also stop making push fall back to fetch. But I think people
would find that irritating.

I dunno. I think there has always been an implicit "subordinate"
relationship between fetch and push URLs, with fetch being the "main"
one. Maybe that is so ingrained in me at this point that I do not see a
problem with the asymmetry.
