You can already do that to a degree for the record.

I left my phone at home accidentally the other day, it wasn't until the work day was over and I tried to remote start my car that I realized, since almost every feature I use worked over WiFi (the remote start checks for the phone's presence)

Yup, the watch piggybacks on WiFi authentication from the phone. Once you store the SSID and PSK for a network on your phone, the watch can log in independently, and you can take/make phone calls and SMS. I've done this when I left the phone at home by accident.

It's not the just the watch. All my devices will connect to a new wifi if one does.
