When working with the API and an object implementing IIBPhonesParent, what do the phones Include options value represent?

There seems are 5 options InlcudeOptions allows (all, default, reciprocal, record, relationship).  Is there any documentation as to what these options do?  I'm assuming it tells what data would be pulled, but not 100% sure.  Just need clarification as to what the options mean and if it isn't set does it use Default?  What does Default do?  We typically would only want to update phone and email records for the individual
It is suggested to use the default option as changes to the phone structure in The Raiser's Edge 7.94 has made these options irrelevant.
