It's a tough call with no clear winner.

I understand F and C passengers who do not like to be interrupted by a constant stream of passengers moving through the cabin (especially those on the aisles, who often get inadvertently bumped and jostled).

I understand flight crews not wanting to have passangers queued before the cockpit doors (reinforcement not withstanding).

Common sense and common courtesy should be the rules of the day:

Where possible, use the lavatory in your ticketed cabin. As a "hard-and-fast" rule, if you are more than five aisles away from the dividing bulkhead, you should head back (more lavs there, anyway).

Where not, or when located in the first five rows, stand at the divider between your cabin and the forward cabin and wait.

And ticketed cabin passengers automatically have first dibs on the cabin lavatory. The Y line can extend from the bulkhead to the back of the plane for all I care, but any F passenger can get up as soon as that F lav door opens and trump any Y passenger at the bulkhead.
