I've updated Section 8.3 (Multipath Transport)
https://tools.ietf.org/html/draft-ietf-rtgwg-enterprise-pa-multihoming-10#section-8.3
with the following text:

"On the other hand PA-based multihoming could provide additional
   benefits for multipath protocol, should those protocols be deployed
   in the network.  Multipath protocols could leverage source address
   selection to achieve maximum path diversity (and potentially improved
   performance).

   Therefore deploying multipath protocols could not be considered as an
   alternative to the approach proposed in this document.  Instead both
   solutions complement each other so deploying multipath protocols in
   PA-based multihomed network proves mutually beneficial".

Thanks for your suggestion!
