+1 - Support as written.

I know +1's aren't strictly needed in Last Call, but I want to explicitly
state that I agree with the AC that sufficient consideration and discussion
was given to the "should" vs. "shall" question before and during the PPM,
and therefore I agree it is appropriate to send the policy to Last Call
(and on to the board, if no un-considered objections are raised) without
another public policy meeting/consultation.
