What do you mean by above board? What they claimed is that there is no way of telling Beeper Mini clients from an old iPhone, therefore Apple wouldn't be able to block one without blocking the other.

Clearly Apple managed to find a way, and who knows if there will be some more cat and mouse happening here. In theory though, I don't see why it wouldn't be possible to have a service that's indistinguishable from an old iPhone.

Newer devices can use device attestation, but old iPhones don't have secure enclave.
