I do agree for the consistent mental model.

I've been playing around switching web-apps and other user programs between devices on a single-ususer facing kubernetes system. Part of that relies on all state being sent to the server for distribution if a device switch happens.

I also have played around with a wrapper functions and that can bubble any callback/hook up to the data for further processing. The client no longer worries about sending actions. The server spys on client actions and performs actions on their behalf.

I plan on posting a blog post about the his soon.
