No. refill-mode could make use of `fill-paragraph-function' rather than
calling `fill-region-as-paragraph' directly.

Look at the docstring:

(defun refill-fill-paragraph-at (pos &optional arg)
  "Like `fill-paragraph' at POS, but don't delete whitespace at paragraph end."

If `refill-fill-paragraph-at' is "like fill-paragraph", how come it does
not respect `fill-paragraph-function'?
If the goal is to preserve the whitespace at paragraph end, that
whitespace could be stored and re-applied after calling `fill-paragraph'.
