Well, some flight sims offer the ability to lock cockpits forced on, to be more simlike, but games like the old Star Wars series just let you switch out if you wanted to, no penalty or anything. Except then, I think you actually lost some instrumentation, but nothing that really mattered in the heat of the battle anyway. We could enable something like forced cockpits, but I would say just let everyone turn their cockpits off if they want, I would probably not want the cockpit on except for eyecandy or showing it off anyway, or possibly for an immersion factor in a campaign. But in multi I usually want every edge I can get, lowered detail for higher framerate, no cockpit rendering, etc.
