It's horrid mechanics, wouldn't recommend it anymore than the one the Padres' reliever from last night uses. Repeatability is the most important factor for any pitcher at any level, and this is not really teachable.
It's an exaggerated form, obviously, but the basics are all there. It gives him the maximum amount of power from his frame. As you say, it has to be repeatable to be sustainable, but I don't really see what makes the delivery so "hard" to perform or repeat -- anymore than Arroyo's weird leg kick. I certainly don't see any part of it that is "contortionist".
All that said, one of the things that doesn't get talked about enough with Lincecum is that he trained specifically so that he could perform and sustain that motion. He focused on flexibility and core strength. Yes, his delivery is unorthodox, but I just don't see what's so amazing about it -- other than its effectiveness.
When I pitched when I was young, I had to use a similar motion because I could only be consistent with keeping my balance if I turned my back to the plate at the start of my windup. Of course, the other way that worked for me was if I threw like a SS charging a dribbler, dropping my hands and throwing sidearm -- e.g. Pat Neshak). Maybe I'm weird, but I certainly don't think the conventional motion is for everyone -- or even most people.
