Use of MDT AF if all router are PE

Do I must use MDT AF wirt RR  if all routers inside the core are PE directly conected ?

 

I tried on my lab  without MDT AF configured on PE (we have only mdt source and pim-sparse mode mapped in interfaces)  all work fine... All PE router have VRF PIN neig with tunnels.
