I like how the Unicode Consortium really doesn't want to accept any more flags, but you can still probably shoehorn them in if you're Apple or Google and you have a glyph sequence that is backwards compatible. One way of getting things done -- just do it.
I knew the details behind this because Windows 10 didn't include font with the trans flag by default, and so it always rendered as flag + trans symbol. I eventually installed the emoji font from the Windows 11 betas and found much of what I read to suddenly be a lot nicer looking.
P.S. I love the effects on this website :3
China really doesn't want to accept more flag emojis. For fairly obvious reasons.
That's true, they won't process any proposals for flags anymore. The first link in the linked post is a detailed FAQ from the Unicode people:
> Flags for countries with Unicode region codes [ie. recognized by ISO] are automatically recommended, with no proposals necessary! [...] the Emoji Subcommittee is no longer taking in any proposals for flags of any kind.
They have a section addressing new pride flags specifically near the end of the FAQ.
