I agree that the only way were going to find out is by actually getting people to agree/disagree to ODbL+CTs. Personally I think sooner is better, since not knowing means people may be either holding off doing some work or doing work that ends up not able to be used.

It's also worth remembering that it's not simply a X% of data is kept  and100-X% of data is removed thing. If for example an object is currently at version 6 and the first four editors agree it could be reverted to version 4. Exactly how that works with data consistency I don't know (relation members disappearing, or reverting nodes that were later made part of a way).
