Possible, but what about the simpler rule "only act on nodes when source is either unset or begins with "tiger_import_dch"? (This rule would exclude a whopping 910 nodes from the 172 million we are considering.) Another option would be to completely exclude every node that has been touched after the import (i.e. operate only on those with the pristine version number 1). That would exclude 4 million nodes from the operation (and leave 168 million to work on). On the downside, that would probably be a bit too conservative and leave some superfluous tags in place, especially where maybe a node has just been moved and the tags not changed at all. But then again, 4 million is nothing in the grand scheme of things and we could still think about those later.
