I guess if they start layering LLMs or similar into their service or accessory interop stack I could see how having the phone running the model could be a big win for latency and availability. Like if Apple Calendar uses a GPT to create a .ics from the invitation text my friend sent me then it could be very handy to do that locally, moreso if I'm using my Apple Watch to actually signal that I want the .ics created.
