No, it shouldn't be modelled at all. The Type II and Type VIIa didn't have them, and Type VIIb and later did. They weren't optional, and you couldn't add them later.
But I also agree if they were going to make them an option in the game then the boats should have been slower without them. No Type IX ever went 22 knots.
