The most recently obtained data is that the objects are no longer here. The 'no data' case matches no osm policy that i know, existing or proposed.

Wrong data is worse than absent data.  Osm has so far only contained current data, so that's what 99.99% of consumers expect to find in it, so historical data is wrong data. That'll remain true as long as osm lacks a good way to store historical data that doesn't confuse the vast majority of users who are looking for current data.
