Came here for similar reasons, WatchOS 10 pissing me off with the UX changes and no way to undo them. The only thing I need my WatchOS 10 device to do is let me quickly switch between watch faces, and they took that away. Instead of raise my wrist and swipe, now I have to raise my wrist, hold my finger on the watch until the screens bubble, oops, did I touch the screen a millisecond before it illuminated since I leave it not on 24x7 for battery reasons, well take finger off and try again, now it bubbles, swipe left or right, tap yet again, and finally I have my desired watch face.
I make frequent use of data presented only in a 'middle' section of a Modular watch face, but prefer to be on the activity screen for fitness reasons. For example, when at work, I like to flip back and forth quickly to see my calendar, which would have been a single swipe and done. When I'm surfing, I like to frequently flip over to a tide chart so I know when certain areas will be getting towards low tide and not safe to be near. When I'm exercising via phone app, I want to see my heart rate. All of these were so easy to get to and from with a swipe, now it's a dedicated raise, hold, move, tap, and again to go back. I've had a few Apple Watches across what I think is five or six years now, I work out, run, ski, surf, mow the lawn, and I'd be shocked if it went to an unintended watch face more than ten times in probably thousands of times I've switched faces. So they seem to have deployed a feature to prevent something that never occurred to begin with, and as a result I'm going to be wasting seconds of time with every swipe, as well as no longer being able to safely do it while driving.
