Where I ride there are lots of little rollers where I want to go up or down a few cogs on the back or switch chainrings. With mechanical shifting I can always do one or the other, but even if that's possible with electronic shifting it's certainly not the default.
Ahh only a short time on it.
In terms of electronic stuff you are way off. Not sure where you got any of that. With Di2 you can set the buttons to do whatever you want or add extra buttons and use synchro shift. With SRAM you can easily add extra buttons and one side shifts up and one side shifts down and hit them both to shift at the front.
Regardless though you generally need two hands to shift most anything we have set up stuff for single handed individuals but it was Di2 or a 1x set up but that is less common and if I am building a bike for eating on it probably isn't a road bike.
