Please don't confuse the matter by treating tagged and untagged notes 
the same.

If somebody is improving the geometry of a way because he is 
interpolating from the available information (may that be GPS traces of 
other ways) then he is doing exactly that, just because he is reusing an 
existing object (pre-numbered sheet remember) to mark a new interpolated 
position doesn't mean it is a derived work (because it is simply no 
different than taking a new sheet of paper with a different number).

Now if you wish to state that interpolation itself creates a derived 
work, please argue that.
