Been doing this for over 2 years now, leaving the phone at home, locked up in the vehicle, etc. It works and works well. Less weight and mass to carry with the watch on your wrist and a simple egg carrying close for the AirPods. Yes you can take calls, respond to texts, send texts, get your push notifications, email, and I can run Pandora from the watch.

How you get both hands on that tiny keyboard? Do you have to say "Hey, Siri, give me really tiny hands for three minutes"?
