I doubt so. The only idea that is coming to my mind is to make Org
mode's `fill-forward-paragraph-function' not move anywhere when not on
paragraph - this will prevent refill-mode from filling anything but Org
paragraphs.

However, this idea will not work because:
1. It will cause infinite loop in `fill-region' that is also using
   `fill-forward-paragraph-function', but expects it to move somewhere.

2. Make it impossible to implement custom filling for non-paragraphs, as
   we do for source blocks (by delegating to source block major mode),
   tables, and comments.
