The Pebble had this feature and I am missing it - but for a different reason than power saving.
I usually don't wear the watch during nights so it just sits in the room beside my bedroom/livingroom. When I don't wear it (e.g. sleeping / relaxing on the couch), I would appreciate if it would not buzz with new messages. This power saving mode was a very convenient way to achieve that without having to mess with do-not-disturb-modes.
