I cant see possibly how "not having a snorkel" would cause more panic ! Snorkels are not needed for surface swimming, are not needed underwater and not needed for scuba diving in my view.
Trying to fold or stuff one somewhere is taking up space other equipment could utilise and is about as useful as taking a cuddly toy underwater - ie no use at all.
