Experience on the line showed the PBA wasn't necessary and was removed.
As far as I can tell there is no note or caution in the new procedure and in the simulator session I don't know if they just RTB with no MCAS and thus don't get into whatever regime it was designed to alleviate. It would seem that they should take the simulator into the relevant handling regime to show the non linear stick force to the crew when they do have a MCAS failure.
