That looks very interesting, but...
That link and its primary source (another journalist) are only speculating that it could possibly be introduced in Android 16. No one from Google is saying that. Or if they are, those articles don't mention it.
That speculation is based on the following facts:
- Google is working on a terminal app in AOSP
- They've apparently been testing that app on 9th gen Pixel hardware
It would be cool if that turns out to be true, but I'm not getting too carried away just yet.
