[Gundam-verse] what is the benefit of having heads for the mobile suits when the cockpit is most often in the chest?

The head houses the main camera (though there are cameras mounted all over the body), various other sensors, communication antenna, vulcan cannons (small caliber cannons used to intercept missiles or damage soft targets), and cooling vents.  

In the 'Future Century' era, during the Gundam Fight competitions, the destruction or removal of the Mobile Fighter's head was one of the ways for a fighter to be defeated.
