I agree, but it’s more complicated than that: They have removed the device tree for pixel devices from AOSP and using the device tree of the basic virtual phone in android studio instead. That brings the pixel 10 family (as well as future android pixel devices) to the same level as many other phonemaker’s devices as far as making roms is concerned. So not all hardware will be documented, many drivers will need to be rebuilt. The pixel line up to the 9a is not affected because older device trees can be used (until Google wants to mod the way drivers load or add API’s).
They are correct. It only means more work for future devices, makes the initial port to a device slower. But then, once things have been figured out. It becomes just as fast and reliable as it was (unless what I said earlier: Google setting things in a very different way in a major update (for example, moving to Fushia, which has been abandoned)
