The IBTA defined the specifications to establish standard wire protocols to 
discover services without having to track all potential services.  The IETF 
does not address how P_Keys are managed only that the IP over IB component 
must follow a set of semantics / operations to enable IP communication; all 
IB-specific management issues are outside the scope of the drafts.

As another person put it - embrace and extend.  The approach being 
advocated is something that will be interoperable and provides a solution 
that can be easily incorporated into all IP over IB implementations.  It 
also clarifies the ambiguous IB - admin management interactions for IP 
communications.
