Two Watches, One iPhone

Clearly says: "watchOS doesn't support wearing two watches at once"

There are many fitness apps that could benefit from information on both wrists. Juggling being my interest.

"Wearing two watches at once" is an important developer requirement to capture the whole of the observables of many activities. Everyone has two wrists.

Are there any fundamental reasons why one iPhone could not support two watches simultaneously, running an integrated fitness app?
From my testing, I've noticed that you can wear 2 watches at once, but only one of them can communicate back to the Watch. If your app doesn't need to talk back to the iPhone or can defer it, you should be good. It is simply a current limitation.
