In a following commit, we will need to aggregate filters from multiple
accepted promisor remotes into a single filter.

Ah, interesting. I was always operating under the assumption that when
the server advertises multiple promisors, the client will pick only one
of them. And that made me wonder how the client knows which one to pick
in the first place.

But of course it's possible to just pick _all_ of them by combining the
filter.

Yeah, that's the idea.

One thought I recently had: if one selects multiple promisor remotes,
how does the client know which promisor remote to fetch a certain object
from? We don't always have enough information about a missing object to
be able to tell which of the filters would have excluded it, so it's not
possible to basically "reverse" the filtering and deduce from them which
remote should have them.
