My idea was to save a verification step - the caller of fetch_object() needs to reattempt the object load anyway (which includes a verification that the object exists), so I didn't see the need to have fetch_object() do it too. > Also I think the "extensions.partialclone = <remote>" config option is > not very future proof.

In the case that they want to talk to more than one partial-clone-enabled repo, I think that there still needs to be one "default" remote from which missing objects are fetched. I can think of a few reasons for that - for example, (a) we need to support commands that give a nonexistent-in-repo SHA-1 directly, and (b) existing Git code relies on the ability to fetch an object given only its SHA-1. (a) can be overcome by forbidding that (?) and (b) can be overcome by an overhaul of the object-fetching and object-using code, but I don't think both (a) and (b) will occur anytime soon.
