By default things should stay as the status quo, how this is
implemented will be the hard thing. With the filtering code that now
exists in JOSM this could be done by editors, but it only takes one
editor that does filter to have a lot of hard work suddenly be
deleted, so realistically this needs server side changes.

Rendering on the other hand will be more tricky, although for most
people this will most likely only need osm2pgsql tweaking to filter
out historical data by default.

Erm deleted or altered the tags? If they still exist, but have other
uses they shouldn't have been deleted...
