I can assure you that I'm always paying attention to protecting the rear derailleur (or any component for that matter) from touching anything, even when I'm just leaning the bike against the wall. I'd say I'm downright anal about it. This is even more true, if that's possible, after I did the first minor alignment 2 weeks ago.

From memory, I don't see the derailleur flexing inward when the skewer is tightened. I'll look at it again today. However, I remember seeing the derailleur somewhat tip inward just at the last tightening 1/4 turn of the derailleur fixing bolt into the hanger. This may be normal. But, it made me wonder if there was some sort of mating anomaly between the RD (5701 medium cage) and the CAAD hanger.

Wheels says it's much stiffer - but they couldn't provide any hard numbers. I'm just repeating what they told me, but wanted to get some feedback from the forum. As I mentioned, the new version of the CAAD10 hanger is thicker than the pre-2014 hangers. There has to be a reason why they suddenly changed the design. I'm no expert, but it seems very few hangers go through revisions.
