My experience in the past year is attendants being much more strict on the "no standing in line for the bathroom" thing. Honestly, I don't understand how this is supposed to work. If we can't get in line, then we have to watch carefully, and as soon as someone leaves the bathroom, jump up and run down the aisle to it. But everyone else who wants to go is doing the same, which means that the person whose seat is closest to the bathroom wins, and everyone else needs to got back to their seats. So people farther away don't get to go, while those sitting near them also grow increasingly frustrated.
