But all of those cases should be governed by a very simple overarching rule: If the laptop lid is closed, assume that it is in a closed bag with no cooling available to it.
Because that is the usecase that hibernate is for. It makes laptops convenient by allowing you to just close the lid, put it in a bag, go somewhere, take it out of the bag, and then open it and continue working. If you need to tell people that they need to shut down their computers properly before putting them into bags, you have just produced a vastly inferior product.
This is an area where Microsoft desperately needs a Chief-making-it-not-suck-Officer. Someone who can just take that surface laptop, notice that some idiot actually wrote that you are supposed to shut it down instead of hibernating to put it in a bag, and yell at people until the product is fixed. Because right now it's broken.
Except your rule isn't a rule at all, it's just you assuming everyone else has the same usage pattern as you (they don't).
Pre-covid I had many co-workers who would sit down, plug their laptop into the dock, and work the whole day without ever opening the lid.
I've also spent 15+ years with a laptop connected to my TV that never has the lid open, and I definitely expect it to wake up when I sit on the couch and wiggle the Bluetooth mouse.
