A Wikidata ID is part of a URL and can be rendered as such; for
example, Q173882 equates to <https://www.wikidata.org/wiki/Q173882>

It's not "unusable"; see URL, above.

OSM is best used for "on the ground" data. There's no point in trying
to use it to replicate all the data held in other databases.

An example I've given previsouly is that the Wikidata entry for
Q173882 (which is St Paul's Cathedral in London) links to the
MusicBrainz entry for the cathedral, and that tells us which musical
works have been premiered there. We wouldn't want to use OSM to store
lists of works premiered in the buildings we map.
