But then there is Di2. If someone is so inclined to go to Shimano’s electronic shifting system, you can add a digital display that prominently shows the gear.
I know Di2 is UCI compliant, although the digital display may not be, but it is somewhat ironic.
But there is some sense to it. The mechanical gear indicators are a bit funky, especially the inline ones. But with electronics it is not an issue; even if it is merely an unneeded convenience for some.
Maybe someday we can remove our feelings from the sport and just ride.
