This then breaks the "one and only one [...] forever and ever" that
Aaron said, above.

Once something has happened in the archive it *has happened*; any "undo"
or "redo" is a further change, recorded in addition to the original.
That's the model on which GNU Arch is founded; a deliberate design
decision.

You seem to be suggesting technical "solutions" to subvert something
that is a fundamental part of the design of GNU Arch.
