How so?  ISTM the problems at hand are (a) we can't add a new CSV column
without causing a flag day for users who may not even care about the
information, and (b) we're worried that emitting all these columns may
result in a performance hit, again for information that a particular
user may not need.  A user-settable column list seems pretty on-target
for solving those problems to me.
