John, I think there is merit to what you are saying.
The one caution I would suggest is that "If something is worth mapping it is worth mapping correctly". Here in Ethiopia I have spent a lot of time adding nodes to roads that were digitized at a coarse scale. Mapping quickly doesn't have to be done crudely. There is no troupe of magic mapping elves that clean up the rough mapping. The next set of HOT projects I will set up will be roads/highways only and then buildings only.
