Agreed. Downgrading some individual packages to stable (e.g. due
to a bug) is often fine (manual checks/fixes might be needed),
but I would never downgrade a full system.

If one goal was to keep some configuration changes in /etc, then
backup /etc, but do not restore it. Just do a recursive diff and
see what may need to be changed again.
