I can see a point here. Say that a compartment floods totally and the boat is on the bottom. It is no where near crush depth. If the total compartment floods, game over. Well, this sucks because the room could be pumped dry. Say that you are in the middle of the atlantic and you get a room flooded to the ceiling. Of course you are out of control and sinking fast. If you hit crush depth first or flood a room first, boom, game over. So laying on the ocean floor with a flooded room, game over, yeah possible you could not get to the surface. If you blow the tanks to surface and that does not work and the room is flooded, game should be over. Opportunity to pump the room and blow tanks to surface should be given. Unfortunate I do not know were to begin within the config files to do this....
