I would think this is focused on the MTB crowd, where the derailleur is a very fragile piece of the kit. As 1x's get ever more expansive, derailleur arms get longer, and there's just so much room to grow. Seems like Shimano is looking into ways to grow into that. If an ever-expanding range of gears or tighter steps between is relevant or not to something is I guess a personal call. I've ridden across the states on a single speed mountain bike, so I may be the wrong person to ask!
