Yes it's additional complexity indeed, though we would use SSM so no RPs in
the core and no inter-as mvpns(so far :) ) so need for RPF proxy-vectors
Yes I'd love to go with MLDP though unfortunately it's not supported on

A lot of complexity, protocol overhead, data mdt scalability, more state,
more bugs, PIM pimping / RPF vector, more RPs in case of sparse-mode... 

If VPN is mandatory I would go MLDP if  supported.
