Well, on AC's 787s, Y and PY can use the (Starboard) galley lav that's in between Y and PY, so this is moot. You can tell how the curtains at that galley area are kitty-corner angled.
What [MENTION=180388]mapleg[/MENTION] is saying is for exclusivity of that lav to be for PY (and J) pax only, if I understood him/her correctly.
There's really at least two "gripes" (if you will) at hand here... one is having no curtain between PY and Y, and the other is (lack of) exclusivity of the galley lav(s) (behind J) to be exclusive to PY and J only.
