filtering-out historical data (date_end doesn't exist or is in the past) is 1 or 2 rules. Any application needs tens or hundreds of rules to even begin to understand OSM (try defining 'can you cycle on this' or 'is this wet' or 'is this visible' in terms of OSM tags)
p.s. I still agree with Andy in 'ease-of-use matters' and with Frankie on 'tags should have time-limits'. It's not trivial like many tag disussions.
