The UK has approved the updated list of countries/territories they'll recognize legal gender corrections from.

They've purged pretty much anywhere that has self-id.

It's still possible to apply for a Gender Recognition Certificate under the old list for "21 days", but I am not sure when that clock starts/started.

Nobody has even been accused of abusing the process, the change to the list was spearheaded by Kemi Badenoch for the sole purpose of hurting transgender people.
