At least in the "push" case I think there is value in saying "if one
ref fails, please fail the entire push, always". This makes sense,
because if a user happens to violate some rule in one thing, they very
likely may not wish any of the push to succeed, and it also creates
problems with whether a push is atomic or not.

For fetch, I could see either method being useful.
