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.
