As I said, a single node tagged as a pub will only show ub on Z-17 or
so. I know for a fact that someone has imported lists of Youth
Hostels from an external data source, and often wondered about lone
nodes in the middle of nowhere created by that import. While they are
not even rendered on Z-17 to my knowledge, this could change any time.

I haven't looked at that but the assumption that from "nothing
rendered on zoom level n" follows "nothing rendered on zoom level n
+1" is surely wrong.
We could still continue using the current approach if it saves a lot
of time though - if you want your pub to appear on the map, then at
least draw a footpath leading to it ;-)
