Yes! I still want to default to accept-language, but asking is key. What is your pattern for giving the user an option? I like this article in that it rejects icons, but I don’t like how they arrive at one language for multiple regions https://usersnap.com/blog/design-language-switch/
We literally just have a box that pops up with "<language> (<region>)" in each of the native languages. It gets saved to a long lived cookie rather than the user's account for some business reasons.
