No shot on it being Xiaomi (or any other BBK brand like OnePlus), they haven't been super great to the custom rom community in some years now.

I would have guessed HMD, but they just pulled out of the US market: https://www.androidauthority.com/hmd-global-leaves-us-market...

However, Motorola/Lenovo seems the most logical partner, they were previously in the Android One program (which was sort of the successor to the Nexus line).
