But in general the fact that data was gathered by a government surveyor with tools an order of magnitude more accurate than ours does not, IMHO, make it less "worthy" of being in OSM.

David, how would you propose to measure consensus from the OSM community?

The process of reconciliation is painful and difficult, and,
unfortunately, rarely is the importer the one making the corrections,
especially in large scale imports. It's not reasonable for someone to
survey all the airstrips in the world, but neither is it reasonable
for a single person to verify all the streets in a city.

I say this both as a previous "bad importer" and as someone who fixes
errors on the map.

Since you feel strongly about imports, how would you go about
preserving their value while reducing the kinds of issues brought up
on the list (conflicts, removal of ground surveyed data, etc.)
