Well, when Rey runs across the landscape in a wide shot, it’s very clearly just a temp effect as she hovers while running in place. (Although there are some comparable shots in the finished version of the LOTR movies.)
The ocean background when Luke talks with Rey at the end are static. And I think there are some un-removed puppetry things, too.

More importantly, I feel the scene is very nice but better omitted. We have already come to understand that Luke thinks negatively about the Jedi and that Rey is full of piss and vinegar. And when this scene is gone, Luke approaching Rey as she is about to touch hands with Kylo rings more strongly as him about to come to his senses and begin to help her.
