This is the type of thing that happens that happens when you make yourself dependent on someone whose goals are opposed to you by making your OS exclusively for google's phones. I honestly don't know why we can't have a system to visualise the signed image source as the default. Put any public key you want in the firmware, show a 32-64 bit fingerprint of the loaded key as an abstract pattern and only boot an image signed with that key.
