OS10 BGP unnumbered combined with PIM.

Is PIM supported in combination with BGP unnumbered on OS10?

As expected PIM works with BGP and static IPV4 adressing on the interconnecting interfaces, but when I switch to unnumbered interfaces the prune/join or BSR election messages don't arrive at the other router as the unnumbered adresses don't show up as PIM neighbours. Am I forgetting something or is it simply not supported yet in OS10?
