It's not a Bad Thing per se, but i think it violates Posix.  You
normally probably would like to keep the atime record, so you can
e.g. wipe out files from tmp areas nobody ever had a look at since
several days.  You don't win much by not bumping the atime, except in
some situations like a newsserver -- but there, you win a lot.  That's
why the option is there.
