While that is true, you just have to design where your Turrets are suppose to be firing~Turrets spin left/right; but can also point up by 45 degrees. When they are pointing up (if they aren't "extremely recessed") the entire bottom is exposed.
For an example, imagine a turret on top a ship with an enemy sitting above the turret shooting down at it. Now imagine a second enemy coming from the side.
Of course there's also the aesthetics issue - I'm relatively selective when it comes looking at exposed bottoms.
Using Mine as a Example, I have it set to benefit more form Broadside engagement, and as such I would turn it so it Lined up like so. Minimizes exposure of the underside :p
Though I do trim the edges of the turret with Hull, just to give it that Lip of detail.
