I know that I find reltuples useful for getting an "accurate enough"
sense of rows in a table (or set of tables) without resorting to
count(*).  I'd be OK with any two of pages, tuples, and density; but
dropping to one would make databases harder to manage, IMV.
 
Personally, I don't have much code that uses those columns;
eliminating an existing column wouldn't involve much pain for me as
long as it could still be derived.
