Byproduct of mobile again! (By the way, ask Siri on Mac to set an alarm or interact with homekit!) But, I take your point.

"Byproduct of mobile." If you need evidence: Swift appeared in IOS first and still is not great on the desktop at all. APFS (not AFS) is the default in IOS, and still in feature preview and pretty unusable in 10.12. It's "expected" it will be released for desktop in 2017 Siri on the desktop is mostly useless, as said here.
Well, it will be when that beta iOS is released.
Besides, it makes sense for any sort of file system to be released first in such a limited manner.
