(LDP Paging) clients must provide hints to maximize the chances of the 
server responding in the most client-beneficial way on the first round 
trip.  I.e. for overall System efficiency.

Kind of like US taxes: you're supposed to file a return every year even if 
it merely shows that you owe no taxes.
Or if you prefer a more prosaic example: telling the barista which of the 
umpteen variations of additives you prefer increases your odds of getting 
a coffee/tea that you actually enjoy, and (all other things being equal) 
increases the happiness of the overall System.
In all 3 cases, the server/recipient cannot force the requestor to supply 
the hint(s), and as a result the server has to handle its absence somehow. 
 But the System owners can apply different labels to requestors that 
provide hints, and therefore work in the common interest in addition to 
their own, even if that boils down to a social mechanism for encouraging 
System-good behavior.
