I think this is all a bit optimistic. E.g. when I last looked a the Sony phones supported by SailfishOS, there was only one old model that had reasonable support. Newer phones would boot, but missed support for many hardware features.

E.g., on the XPERIA 10 IV, the camera and mic doesn't work, which makes it hard to use as a phone:
