there will be some damage after the rebuild process.
There will be many *wrong* things in OSM after the change. Disfigured
ways that have lost one or several nodes; roundabouts that aren't round
or buildings that aren't square; forests that self-intersect; ways that
were closed but aren't now; former T-shaped junctions where both streets
are now not connected any more.
I'm not as concerned about nodes or ways entirely missing because *not*
having some information is less of a problem than having erroneous
information; but still ways that go missing will occasionally break a
relation or cause a routing engine to go crazy.
Much has been said about remapping prior to the license change but what
kinds of tools will we want to have to help us *after* the change?
Will we perhaps want some kind of logging output from the bot that runs
Some operations - e.g. "removed a start/end node from a way" would
almost definitely lead to someone having to check on the result because
such an edit is likely to break an intersection or open a formerly
Some things would not be precisely loggable because the log would then
have to be CC-BY-SA licensed, but even then one could could record of
often certain operations happened in a given map square or so.
