No.   It's a bit speculative for me, having only done it once so far
and not needed to go back.

Obviously, for "active versions" -- things you might want to merge to
or from -- keep those entirely.

Inactive versions can be discarded entirely -- although it might be
desirable to keep even the inactive portions of what you consider to
be your `mainline' pedigree.

I like to make ChangeLogs for various versions before doing this so
that, in principle, less information is lost.

Is it desirable to add a mechanism that records "gone but not
forgotten" logs?   Perhaps so.... but it's tricky (supposing, for
example, that I later do something that would revert and remove some
of those logs if they were still around).
