I've never needed to worry much about the speed difference between rear and front changes so it didn't occur to me. I do understand the ease of one chain ring chage instead of multiple sprockets. But then almost all my riding has been done with friction shifters. It seems that with programmable electronic shifting "ease" is pretty much guaranteed.
Why not? The roads are pretty well mapped out.
But on the original post, I think it's a good question. Electric shifting could shift both gears as easily as one, and I'm skeptical about a delay or lag on the front being a significant drawback. I'm inclined to says that it's purely market resistance and not technical.
