The main difficulty at that time probably was the SQL to return the 
"latest version only" of each object. Matt won't have that problem 
because even if he wants to return deleted objects, he can ignore the 
history tables - we have the deleted objects in the current tables as 
well. (Plus, you didn't have people with a degree in aeronautics. And 
very few Germans.)

Someone suggested in the run-up for the 0.6 changeover that we could 
drop the deleted objects from current because he didn't care whether he 
gets a 404 or a 410 return code. It sounded ok at the time but I guess 
that it this were done, returning deleted objects would indeed be a pain.

Bye
Frederik
