I think that post has successfully caused my brain to melt into a puddle. XD I don't have a problem working with the overshoot. Ive become quite accustom to how it works. Its really easy to adjust curve with a couple edits. idk about the lingo, but with the end key cause it to act linear, if you just drag it to the left 1 frame it creates a nice curve.
I would hope they fix the several game breaking issues that keep me from moving from 2014 to 11 before they dive into changing the curves. 11 has become less animator friendly imho. Hopefully its only temporary.

EDIT: Nevermind. I just glanced at the first images again and see you already know what Im talking about with the curves.
