Would those be referenced by planned dives? Or do you really mean 
"unreferenced", i.e. you create a dive site, save the dive file and quit the 
app, and then later add a dive at that site?
Just making sure I understand the model you are proposing.
The issue with not pruning unreferenced dive sites is that over time you might 
accrue a lot of garbage in your dive file. E.g., whenever you dive with a 
Garmin Descent or similar dive computer (there are none right now) that store 
GPS data, that creates a new dive site. Typically I then switch to the existing 
one if I have been at this site before, which creates an unreferenced site. 
Having all of those accumulate over time might be annoying.
