Well, if someone accidentally merges 2 ways with different names, you need a
"way back machine" to see what each part was called before his error.
Detecting all changes can be as simple as comparing the current vector data
with the vector data at a chosen historic date. Hiding trivial changes are
not important at this stage.

In many cases reverting may only be possible by manually redrawing the whole
area, but I'm OK with that provided that I can see the map at the chosen
date.
