Even though that is my perspective I like that you remove the mention it TFA. The reason why being that I think Snoke doesn’t decide that he needs more training until he sees him at the beginning of TLJ, when he sees how conflicted he still is.
EDIT: I also think it is funny how Snoke starts going on this aside and Hux is thinking, “That’s great and all but I can’t stand here and listen to you monologue because the collapse of the planet has begun.”
