Though we have not yet added support for multiple language tags, we have added more than 350 new options that we think may help out with this particular ask.
For more information, you can take a look at our blog post at https://blog.twitch.tv/en/2021/05/26/celebrate-yourself-and-your-community-with-350-new-tags/. Thank you for your feedback and ideas!
We will leave this topic open for now for further discussion around whether this meets the needs of the request.

This is an excellent idea, BUT the tags could be potentially applied to the topic being discussed in the stream and not being used to represent the streamer.
