Lets say you fighting some pirate who manages to destroy some of your hallways why the nearest toom start to act like there was no hallway at all and just close up eith walls? isnt it should be a breach to the insides what would make all air go outside if theres no doors that could close it up?
This would add the need to make more like doors in hallways to ensure that the destroyed part eouldnt kill your ehole ship crew bcs of lack of air.
And if you cant afford that much of doors then crew must have something like space suits to wear them in such conditions, also this hole in your ship would make a great acces for the enemy crew to go raid you.
