On OHM these objects need to co-exist ... if OSM is going to create yet
another version of the historic object if recovering from the change log
we are going to get into even more of a mess. This is why 'delete' *IS*
the wrong concept for objects that CAN be authenticated historically.
The whole problem here is that objects like railways are going to evolve
over time, and while some elements may no longer be visible, maintaining
the sequence IS important even if some people think that there is no
place for that information is OSM.

I repeat what I have said many times before ... we are documenting that
very history today, ad while the information is available from the
change log, it ALSO needs to be directly accessible from the OHM view so
why not simply maintain that information in a format that the CURRENT
rendering tools can show and the current editing tolls can improve on.
The change log is simply the wrong place for this data to exist in ...
