  Yes, [sadly] deprecated by the Unicode Consortium in Unicode 5.2, and by the IETF in RFC 6082. Nor have they be undeprecated since them (see https://www.unicode.org/versions/Unicode15.0.0/ch05.pdf#G11552 https://www.unicode.org/versions/Unicode15.0.0/ch05.pdf#G115...). IMO we should have tried harder to make Unicode language tags useful and used. But it didn't happen, so they're a thing of the past. Of course, they're still there, and one could attempt to resurrect them, but most likely one would fail.

    Oh, “tag” made my brain parse as HTML tags. TIL
