I can't imagine a use for a relation or multipolygon with no geodata and no
tag data, even when considering multi-day edit sessions. If someone isn't
going to provide some information (at least tags) then why would they make
the relation at all?

I wouldn't suggest using relations or MPs with no geodata and with tag data
over long edit sessions since if you lose your spot and have to redownload
from the API you'll of lost the relations unless you remember their IDs.

I might propose something at a later data dealing with relations or MPs that
have no geodata but have tag data, but that's not the purpose of this edit.

Just for reference, there are approximately 5k relations with no geodata.
