You don't need an additional key in OpenStreetMap to find wikipedia=*
tags pointing to disambiguation pages. By parsing the content of the
Wikipedia page and checking if the page looks like a disambiguation page.

And even if detecting disambiguation pages in Wikipedia would miss too
much of them, you could use Wikidata to check if the Wikipedia page the
Wikidata item points to is a disambiguation page according to Wikidata?

While wroting the paragraph above, I wondered how the status of a
Wikipedia page a Wikidata item links to is maintained. Is there a bot
updating them every hour in Wikidata? If there is no such bot (or it is
not running every minute or hour), there is no need for wikidata=* tags
in OSM to find wikipedia=* tags pointing to disambiguation pages because
you could get the status of a Wikipedia page by parsing the Wikipedia
page itself.

Best regards

Michael
