Mmm I don't see any current use of the copy keyword argument inside the as_variable function. Here is the only place where I found copy to be explicitly provided. Can I safely remove it also there?

Yes, we can safely remove the copy argument here. At point point, as_variable did not always return a new Variable object, but as you can see it always does that now.
