Maybe they are trying to discourage pilots from *requesting* a more
convenient runway by giving them an explanation of why they might have
gotten a sub-optimal assignment.

If a pilot insists on a certain runway clearance, he might have to
wait, but I don't think the airport can deny the request for reasons
of noise abatement; hence a little nudge-nudge on the ATIS along the
lines of "help us to help you."

Just a guess.

"...aircraft are requested to use the assigned runway for noise abatement.
Advise the controller on initial contact that you have information Bravo."

WTF? How can they NOT use the assigned runway at a class B airport?
