Right. What is stopping Apple from requiring a valid unique device key with every request now?

Old hardware that doesn't have it. Are they gonna ban my iMac from 2009 that was before iMessage was a thing?

Yes, they are. You already don't get OS updates.

No they aren't. My iMessage still works, and so will other devices that had iMessage.

just because it works now doesn't mean it will tomorrow. You're on officially unsupported hardware / os version.

Ask someone with 32-bit Mac apps about Apple’s willingness to leave parts of their userbase behind.

They still work. Apple doesn't stop services from working or programs from functioning.
