Honestly, look at what was done with the Star Trek reboot movies. They completely obliterated "canon" while still making great movies that absolutely feel like Star Trek -- Except of course for the lack of Shatner Voice.
I think this move really is just about finding a way to make movies they feel are great without having to worry about "But, on page 137, paragraph 2 line 3 of (insert favorite book here) it says that this scene in the movie couldn't possibly happen!" (and admit it, while that's obviously an exaggeration, you know it would happen. ![]()
Now they just don't have to worry about "Will this be bending canon too much?" Instead its "Hey, it flies because the movie is, by definition, canon."
