If there is intent on manned guns affecting score/deaths/perks...
A waste of time. You could have a manned gun death count as a billion deaths and put your score in such a bad shape that it would take a full year of playing 12hrs a day or account deletion to fix, won't keep me from using them. I don't care about score, nor am I going to start.
The only thing you are doing with a wish like that is wasting Dev time for nothing.
As for the OP, if I am reading it correctly, wouldn't bother me either way. Does make sense, truth be told. Though, if your ship is sunk, but your gun wasn't destroyed, then your names in lights. Think of it as abandoning ship. If your gun is destroyed when the ship is sunk, then you don't get name in light.
