Non-Apple devices could just lie

  Beeper will know only a small number of valid serial numbers If it ever becomes popular, there will be a lot of duplicate serial numbers. That's easy to detect and ban.

  Not if they require a certificate containing the serial number/imei/... + a nonce provided by Apple, signed with a private key/certificate stored in the secured enclave, loaded into the device when it's manufactured.
