Probably that suggestion/rule is followed by some parts of the UN and perhaps some documents from a few foreign ministries. I certainly hadn’t ever seen it in the wild until the GP comment. It made me chuckle…not at the commenter but at the country.

Also it's 2023 and people know how to deal with tricky alphabets and stuff now.
Not saying it's wrong to not deride someone for using the proper spelling but the existence of the French forms shouldn't inherently require forms from languages without significant influence on English.
They asked for it to be changed, and got what they asked for. Both the UN (https://turkiye.un.org/en/184798-turkeys-name-changed-türkiy..., https://en.wikipedia.org/wiki/Name_of_Turkey#Presidential_ci...) and the USA (https://www.dw.com/en/us-officially-changes-spelling-of-turk...) decided to change that spelling.
Don't you mean artillery from Deutschland? :)
