That's true, but hopefully at this point it's clear that actually
getting rid of a branch permanently would require rather a LOT of
work, and that even if someone deliberately did their absolute best to
get rid of a branch, an experienced git user could put it back in less
than 15 minutes.

I actually think a more likely scenario would be: we deliberately
remove a branch - and then someone accidentally re-pushes it.  But
since we have no plans to actually do any such thing, that risk also
seems more theoretical than actual.
