Yes. And looking and the full history is always an expensive operation, 
hence the plugin relies on the wtfe.gryph.de service and that, in turn, 
has only a minimal database that contains the id of the user creating an 
object plus an unsorted list of user ids of the users who touched it 
later on.

I think that "clean" elements should not be marked at all. Clean is the 
default; no action is required on a clean element.

Declined or undecided.

Well: If v1 of an object is done by someone who has agreed to ODbL, then 
it is absoultely sure that *something* of this object will remain. If v1 
of an object is done by someone who has not agreed, then it is *not* 
sure that something will remain. Don't you think that it makes sense to 
distinguish these cases?

Yeah, and the pub inserted near an intersection is a dervied work of the 
intersection... if we listen to that kind of argument we can just colour 
everything orange and be done with it - no database required ;)
