Is that really a concern? Maybe, but also Git will never move data like
that.

I would say that we can safely say that this year ;-) as dumb HTTP
would be mostly dead.

We do fetch the refs first for dumb HTTP so last I checked, we correctly
detected this case and failed.  I'd personally be happy to let the
DAV-based protocol die, but there are folks who like it.

I didn't mean DAV.  

The oldest dumb HTTP code grabs all packfiles listed in
objects/info/packs and there is nothing to prevent folks from
running the current client to fetch from SHA-256 repository into a
SHA-1 repository.  The resulting packfiles that do not identify with
the version number what hash it uses would be very hard to use.
