I am considering creating a new proposal for Stack Overflow in Thai language but, from what I have done the research, this post is the most recent information I can find where it means that the system will not accept new proposals for new Stack Overflow language sites anymore.
The question is that -- is it acceptable now?
No, nothing has changed since then and there is still nothing planned. We will not accept entirely non-English site proposals.
For future readers: we will announce if this ever changes. We won't secretly decide behind the scenes that we're going to allow it again and wait for someone to propose one. If you're not finding anything more recent, it's because there is no recent change to discuss on it.
