Since the whole idea of MPLS MS-PWs is to facilitate the interworking of
different
operators, as far as I see coexistence must mean either

1) fully interwork
2) mandate that they never have to cooperate.

The latter would probably end up with everyone
having to support both signaling protocols, 
and often setting up additional PWs just to circumvent
the limitation.
