I agree that the only legal sound way to do it is by removing all 
dependent data. But we can't even tell what data depends on data from 
contributors who didn't give permission...

Suppose I split a way into two parts. The second part now gets uploaded 
as a completely new object, with nothing in its history pointing 
towards its origin.

Or another example: I can align the outline of a forest to the road 
which I know is its boundary. So the forest is also a dependency, but 
not a single clue in the database the two might be related to each 
other.

That's all becoming quite a minefield really.
