I finally broke down and loaded the iOS 11 first beta on my new 12.9″ iPad Pro this weekend. Unfortunately, with this being the first version of the beta, doing so has pretty much rendered this device useless other than for testing the new OS. Several apps are crashing, and there are plenty of rough edges, just as you would expect for a beta release at this juncture. However, one thing I have noticed is that Multitasking is actually pretty polished, even in this initial release. Multitasking has triggered a few crashes, but it is stable for the most part, and the scrolling, gestures, and motions are all fluid and work well.
