Really? I thought that it could be a useful data for "advanced" uses.

You are saying about libibnetdisc itself. My example was about an
application which uses this. For instance after discovery application
may want to query some ports for its own purpose. What is wrong with
that?

I cannot understand why are you trying to make things there as "private"
as technically possible (even on price of extra code size and
complexity). Finally it is an open source stuff, so let to users to use
it how they want and for their own responsibility. :)
