This is simple. fill-region has

(if use-hard-newlines
	    (progn ...)
	  (fill-forward-paragraph 1)
	  (setq end (min max (point)))
	  (fill-forward-paragraph -1))

So, `fill-forward-paragraph-function' is currently ignored when
use-hard-newlines is non-nil. With the proposed new
`fill-region-as-paragraph-function', it will still be ignored, AFAIU.
What I am asking is a way for major modes to customize boundaries even
when use-hard-newlines is non-nil.
