Ryoko would still let the player do it even if she's awake, (spoiler possibly:) like when you interact with her on the table, she even does the same with the player when you click "Sleep until morning" or "Sleep until morning with Ryoko", after some certain things to unlock it----So, yeah... I don't see much of a problem.
Also it's not a new one, it's kind of there already before the update.
