Who said that? Where? Who has now said that they *will* replace OSM tags?

"Scary"? Again, please tone down the rhetoric.

Yes, it would make good sense to use Wikidata for translations, in a
number of circumstances. I have no idea what, say, the Croatian for
"raiwlay station" is, but I bet Wikidata does.

OSM already does not exist in a vacuum; I see no problem with
interdependence, just as Wikipedia is increasingly becoming dependent
on OSM of its maps.

It does not need to be "self-explanatory"; we have a wiki to do the
explaining; and editing tools can also do that.

We equally have many other tags, which a given contributor may never
have heard of.

Nothing would /prevent/ them; there is much that is not prevented, but
which is still not wise, or useful.

What others? We should accept - or not - each tag depending on its
usefulness to the project. In this case, it is more useful to let
Wikidata do the heavy lifting, and for us to link to the place where
they have done so.
