Ed, I don't quite follow your logic.
You seem to be saying: 1. there is no proof that CC-BY-SA doesn't work; 2. there is danger that anything based on contract law weakens the protection we have for our data (because breach of contract doesn't give us a strong handle) 3. you accept that CC-BY-SA uncertainties may have turned off some potential users 4. you would happily go along with dual-licensing OSM under CC-BY-SA and "some other, more permissive" license. Is that a correct sum-up? If so, then would not the "other, more permissive" license you are willing to grant in 4 automatically lead to the weakened protection from 2? "Dual licensing", after all, means that the licensee can choose any of the available licenses and not be bound by all the others he or she does not choose.
