Sleeping beside polar bears

Polar bears are extraordinary and should be well respected. Picture this, your in a snowy biome without a bed and it’s getting dark but you come across a polar bear walking around. I think it would be breath taking if you could go into sneak mode and approach the polar bear slowly , as if to show your friendly and mean no harm, to which if you don’t then it attacks you. when close enough you give them any piece of meat or fish. After this the polar bear could have a less than 50 percentage chance of laying down to which the bear is displaying respect and trust towards you and so that you then have the ability to lay beside them to sleep. From the bears warmth it could grant you a bonus like filling up any lost hearts, or even an item like a tuft of polar bear fur that malted in the night ( this could be used in potions ) I just feel that you would feel so amazed if it allows you to shelter with it and would make the player form a respect for the polar bear in return. This could even be a way of slightly taming the bear after it bonds with you but that it doesn’t follow you, just doesn’t attack you when not in sneak mode and attacks a mob attacking you, and Let you sleep beside them whenever. Overall I believe this would give a unique ability to the polar bear, whilst still preserving their solitary and honourable characteristics.
