Not sure I agree with you on that. If the elbows are placed on the pads, extensions are put at the correct length and the angle of them places the shifters just high enough it essentially achieves the same thing you're talking about ime. Of course it's easier to angle up the pads and the extensions independently of the base bar but it's not always an option. I actually prefer the elbows further out most of the time anyway for comfort and because it can help make it easier to hold a good position(especially if cockpit position is narrow). Not saying this to convince you(and I probably couldn't anyway!) but to give a different alternative to at least try for those who are experimenting with the angled forearm approach but can't angle the pads easily.
