Conflicting opinions are generally from people that keep perpetuation the myth that if a snake is fed in the enclosure he will be cage aggressive.
Snakes should be fed in their enclosure for their sake and for yours as well, moving a snake that is in feed mode is the best way to get tagged, with BP in particular it can also be stressful enough to lead to refusal.
Trust me on feeding day I would not venture in putting my hand in my snakes enclosures let alone picking one up to transfer it to another location, with a strong routine they can be conditioned to know when feeding day is and can be on feed mod from early during that day to hours after their meal.
