>>> My view is that we would be missing an opportunity to have mappers review these locations and update the areas concerned. These nodes exist mostly in ‘undermapped' / remote areas that could use some human mapper attention. So I’d be in favor of trying to resolve this using some human driven cleanup first.

Moving data to OHM from OSM requires
(1) deleting data in OSM
(2) importing data to OHM

And importing GNIS to OHM would work better if it would be imported straight from GNIS rather
than from partial OSM data that was transformed GNIS data.

Also, I would be surprised if OHM still has no GNIS data.
