Whuh. I'd fill ONE watch face with my most often used/important widgets, then stick the other ones in the dock - which is exactly what I've done with my watch.

Repeatedly flipping between faces would make me go buggo, honestly.
Personally I would be super happy to see at least one of the changing faces side-swipes replaced with fly-out music player side panel instead.
So pick a different face then. It's not as if it's a bad thing there's more choice now.
Personally I always disliked that the maximum number of widgets you could get was 4 tops on most faces, and typically even less. Exercise rings face has just 3 user-defineable widgets. Getting up to 9 is a huge step up.
Apple is undoubtedly aware that their approach up until now has been conservative to say the least, and thus deliberately show off this particular face to let widget-loving people know there's now at least one option for them too.
