Thank you for something BICYCLING related! LOL
I found the image with the derailleur hanger between the frame and the cassette to be pretty interesting. I(t's the first image that doesn't have riders in it. I've never seen such derailleur a setup before.

It's a 'thru-axle' set up. They've been around on MTBs for quite a while. They offer greater stiffness at lighter weight. It's one of "standards" that aren't (like various BB 'standards'). The UCI has been allowing them in lieu of open dropouts with 'lawyer tabs' so expect to see greater cross compatibility as time goes on. Here's a primer on the technology:
