I look at it this way: until recently, we were quite accustomed to our road bikes featuring cables sprouting from our handlebars. Now, in no small part due to electronic shifting and hydraulic brake cables, it seems almost barbaric (IMHO) to see cables up front. Virtually all high-end bikes are featuring a front end that hides the cables from the wind and the eyes.
I think the current design for road disc brakes was simply carried over from their original application - MTB - many years ago where aero was not a consideration and when aesthetic standards were different.
In 2020 - soon to be 2021 - it seems like an area that can and should be improved. After all, which seems more likely to be the road/TT disc brake standard for future bikes, the photo posted above or the photos below?
