BTW, why does it bother you how others shift? In some kind of chain preservation society?
This. It's one thing to ride cross chained continuously, it's another thing to just downshift at a light, stop sign, or brief stop. Dropping from the big ring in the front, means I have to shift the back as well to keep a smooth pedal stroke and the opposite to get going again, especially if I want to go quickly from a dead stop. Just shifting the back is so much easier.
Not to mention, with Di2 shifting the front uses more battery than shifting the back.
