Looks like the priority lines for D1, 360, Diamond and First (!) are going to be rolling out to more locations:

I understand priority given for D1 since lounge access is part of the product being sold (and that will be moot in time at JFK and LAX with the new D1 lounges opening), but surprised they would prioritize domestic F passengers who aren't necessarily members, over paying members.
I thought domestic F (not D1) in and of itself did not qualify for SC access.
