Tank aggression due to feeding in the home enclosure is a myth. In fact, you are more likely to get bit if you feed your snake in a separate tub because it will associate being picked up with being fed, which is the last thing you want.
Keepers with a large collection feed in the enclosure for convenience.
Keepers who have giant snakes such as reticulated pythons, burmese pythons, or anacondas, feed in the enclosure to avoid ER visits.
Keepers who have venomous snakes feed in the enclosure to avoid trips to the ER or morgue.
I have a few adult retics that are 14-16 feet long. My biggest female is 100+ pounds. Every one of them is fed in the enclosure. None are enclosure aggressive.
Now, you are more than welcome to come to my place, pull any one of them out of the enclosure to feed it, and then put it back afterward. I just get all rights to the video footage because it's going on YouTube.
