Personally, i think this mod should be integrated into the game, because it brings about the things the dev hasn't come close to recreating, such as smaller single AA guns, quad barreled AA guns, the mix of metal and wood, the searchlights and everything else that's just so good. Without this mod, recreating huge battleships gets kinda hard, because you'd have to dedicate an entire section of the entire ship for one gun if you were to recreate it 100% historically.

agreed

I think it should be integrated too partly because it also makes making small tanks and ships easier.
