Makes sense. If we keep all trees and commits locally, pack v4 still
has a chance to rise!

Although for git-gc or git-fsck, I guess we need special support
anyway not to download large blobs unnecessarily. Not sure if git-gc
can already do that now. All I remember is git-repack can still be
used to make a repo independent from odb alternates. We probably want
to avoid that. git-fsck definitely should verify that large remote
blobs are good without downloading them (a new "fsck" command to
external odb, maybe).
