I can always add another by force-pushing a tree with a single commit,
garbage collecting and then pushing regular commits on top, which
should be able to reuse previously existing hashes.  Even if not, since
we identify a repo by URL, I could ask the forge to delete it and then
push a completely reinitialized repo under the same name.

Speaking about destructive operations, there is one course of actions
that an upstream could take if they deem 2^160 to be too small an
address space, which would be sane for consumers using tags, but insane
for those using commits.  And that would be squashing all the commits
between two tags to a single one, correctly reapplying tags and (force-
)pushing the resulting repo.  Though again, the blow for commit users
might be softened through git vanity this time :)

I'm not saying the above should have any impact on what we feed to git-
fetch, but it's a fun shower thought.
