I’m really curious about how it was detected, how it was different from Apple devices. If nothing else I’m looking forward to reading about how that all worked.
It is usually easy to detect a specific client. Like even if you ignore the keys there are dozens of little details like the TLS fingerprint of whatever library they use not matching iOS. Things that are easy to miss and sometimes hard to bypass. Then there are heuristics on how it is used is likely unique.
From what I understand, their guess is that Apple is now checking if the device also has support for other services, such as FaceTime. Beeper Mini and pypush don’t pretend to support FaceTime, so it breaks.

I’m just surprised that it took this long
Probably had to be extra careful to test. MDM software software might get glitched out.
