I think Russ is on to something with his "ClosedStreetMap" concept although that is some terrible branding so we need another name :) But at the end of the day, we are terrible at maintaining such boundaries and very good at breaking them in OSM, mostly because they are usually hard/impossible to spot on the ground and verify. So people see random lines going through the area they are trying to map and either don't pay attention when they touch them or just delete them outright. Essentially what we need is the concept of layers. If all the admin/timezone boundaries were in their own "layer" and didn't interact with roads, rivers, etc in OSM then they would be much easier to keep up to date from external sources.</blockquote>
</div><br>Introducing layers, although difficult to implement, would certainly simplify editing. Moving admin boundaries and land use polygons to a layer(s) would simplify basic editing. No more connecting roads to boundaries and land use edges. Layers could even introduce the concept of limiting permissions to edit. <br>
