If you're actually doing the correct locking and packed-refs read (which
"real" implementations like libgit2 do) then no, I don't think that's
dangerous. And I think libgit2 properly complains when it sees a
repositoryformatversion above 0. I don't know offhand about JGit, or any
of the lesser-used ones like dulwich or go-git.

Today, some of these sound like shortcuts that are very likely taken quite a
bit by cleanup and other maintenance scripts (not necessarily formal git
tools), and the impact of these shortcuts is likely low with the current
model. However, I suspect these tools/scripts could be seriously disruptive if
we leave the refs dir around when using reftable,

Maybe we can leave the refs dir, but have no heads/ directory inside,
and make the whole thing read-only?
