What's the delay? Mew Gull >> Short-billed Gull

Description of problem (please provide a set of steps we can use to replicate the issue, and make as many as you need.):

It’s been at least two months since this taxonomic update was announced, but it was never implemented. This issue is urgent. See https://www.inaturalist.org/taxon_swaps/99242#activity_comment_a1e0a928-9b66-4939-98c5-903fb55b01ea

Hi @joseph103, the main topic about these bird taxonomy updates is here: https://forum.inaturalist.org/t/2021-clements-update-and-continual-concerns/25875 (although in general commenting on a flag or taxon change is the typical way to discuss specific taxon issues). Since this isn’t a bug with iNaturalist, I’ll close this report.
