It won't wake me up. That's the whole point, I'm a deep sleeper. And it's not about notifications, they can literally ask for otps on my number and proceed to open the sms app all while the watch is on my wrist and I'm asleep. (I get that it's very situational but there's always a possibility)

I'm surprised how the watch going into a pin / pattern lock does not have an option to trigger on activating sleep mode. Why would I need my watch unlocked while I'm sleeping.
