You might be able to treat `simple` as more of a special case (to the extent that it ever makes sense to link to it from OSM). None of [the other language codes](https://github.com/osmlab/wmf-sitematrix/blob/dae8cfcc1bb414fd225d0c04da422bc7af807a02/data/wikipedia.json#L3) gets so long before the first hyphen.

I think it’s safe to drop this special case. I had no idea anyone is still using it.

If we also handle subkeys like `wikipedia:fr=*`, then I think we could get away with dropping support for those as well. Occasionally, there are [local proposals](https://community.openstreetmap.org/t/bulk-edit-announcement-addition-of-wikipedia-en-he-values/111842/12) to systematically introduce the language subkeys due to official bilingualism, but `wikidata=*` is the preferred solution for language-agnostic Wikimedia linking these days.
