Is making a big deal of this a new thing? Who actually rides fully cross-chained like that?

BITD those came with a cam operated binder bolt. Heading downhill you would loosen the bolt, lower the saddle, and go. On the flats and uphill, you would loosen the bolt, the seat would come up to the correct height without any faffing about. Now they're battery operated from the shifter.
