Re: [PATCH v2 1/1] setup: recognise extensions.objectFormat

Putting code in master is OK; we can always refactor it. But once we
add and document a user-facing config option like this, we have to
support it forever. So that's really the step I was wondering about: are
we sure this is what the user-facing config is going to look like?

Yup, that is an important distinction.

But that's sort of my point. It appears to be working, but the
prior-version safety they think they have is not there. I think we're
better off erring on the side of caution here, and letting them know
forcefully that their config is bogus.

At the same time... there's extension.partialclone in pu and it does not
have check on repo format.

IMHO it should (and we should just do it by enforcing it for all
extensions automatically).

Sounds good.
