> Unicode's mission is to be able to represent all written text. Once you decide that flags should be part of that you kind of have to include all of them.

Unicode has decided flags shouldn’t be part of Unicode.

There are a few flag emoji that got included before they reached that decision and there are “regional indicator symbols” that often get displayed as flags, but that’s it. They won’t, for example, include flags of cantons of Liechtenstein.
