Good point.  Added.

Basically, the ones I could remember us needing to ask about on
multiple occasions, I put back -- provisionally.  If someone thinks
they're pointless, I won't worry about them being dropped again:
time zone, character encoding scheme, character set, and collation. 
I'm pretty sure I've seen us ask about all of those in trying to
sort out a problem.
 
I also tried the query on a newly installed HEAD build which had no
manual changes to the postgresql.conf file and found a few others
which seemed to me to be worth suppressing.
 
I took my shot -- anyone else is welcome to do so....  :-)
