If we just rewrite those branches to have non-standard branch paths
(e.g. refs/tags/old-branches/<whatever>) the history will be preserved
but hidden. For example, you won't see these tags when you do a default
checkout. Then anyone who wants to "re-activate" the branch can just
create a new branch on that commit using a standard path, or rename the

I think this is probably the right way to go: rewrite all branches but
develop and master (are there any other branches that deserve special
status?) into a non-standard path. If we can determine which tags are
actual release tags, we might want to rewrite all the others into
non-standard paths.
