I think Walter makes a fair point, but on the other hand, issues with TIGER
data are easily apparent when looking at the streets (ways aren't straight,
curves are messy, intersections aren't square, etc.) or when armchair
mappers compare them to the imagery. If they're wanting to figure out which
ways may need review for geometry, the variety of philosophies on the
tiger:reviewed key should allow a search using that (since the most liberal
user usually removes the key after they fix geometry while the most
conservative leaves it until on-the-ground checking is done)

Other fields (like speed limits, surface, etc.) are only going to be there
if a user added that data at a later date. If someone's looking to add
those missing fields, I think they'd be more likely to run an OverPass
query or do a simple JOSM search of the objects in their dataframe rather
than going by the date it was last edited.

I think this is a great idea. To address Walter's point, I would think
about using a special username for this project (like TIGERzipremoval or
something) and making sure your changeset comments cleary state that it's
an automated edit to remove the obsolete tags. That way it's easy to see
when anyone pulls up a way's history.
