Do you think that the set of queries to "the network" for which the
asker really wants and can trust the answer is empty?

There are certainly lots of ways to go wrong, but it seems that there
are times when an entity knows the right question and knows another
entity that has the information and is trustable, but there's no
protocol to ask the question.  If those cases exist, it seems like it's
worthwhile to be able to ask the question.
