Objects are dependent on each other and new, legitimate edits can happen on top of damaging ones which we would not like to revert automatically.

Yes, there are tools in place which can revert edits, but there is still manual checking required. The annoying thing is that companies sometimes go ahead and "invest" money into edits which turn out to be garbage and then volunteers need to revert or fix them up.

There are also a couple of subtle details of the OSM editing model that could make it a lot easier for a knowledgeable vandal to make changes that are rather more painful to undo than they should be.
