Yup! I've gotten one from the AppleSeed stream. Already sending feedback!
I’m going to take a guess that the profile is only installable on homepods that have AppleCare+ because the software cannot be rolled back if something happens.
Every profile from Apple is signed by AppleCare (all public betas, developer betas, AppleSeed betas)if You look when installing the profile it says the profile is signed by AppleCare.
