The only thing that is hard is to clearly define _what_ are the new
anchoring points.
It cannot be "anything directly under .git that has all-caps name
that ends with _HEAD". The ones we write we know are going to be
removed at some point in time (e.g. "git reset", "git bisect reset",
"git merge --abort", etc.). We do not have any control on random
ones that the users and third-party tools leave behind, holding onto
irrelevant objects forever.
