Clearly the restored state of these objects (with a name of "closed") is incorrect, but the way that they were previously processed in https://www.openstreetmap.org/changeset/149843868 was obviously wrong.  I'm restoring to the state before so that people can figure out how best to deal with them.

In some cases "disused:amenity=blah" will make sense; in some cases deletion will make sense (but not in all cases where https://www.openstreetmap.org/changeset/149843868 deleted things, for example at https://www.openstreetmap.org/way/684681276/history there is surely something on that site now, even if it is only a disused school or a bit of brownfield).
