In the 1968 book "The Making of Star Trek" by Stephen Whitfield and Gene Roddenberry, a simple exterior schematic identified the Big Dish on the front of the Enterprise's secondary hull as a "main sensor". There was do direct discussion of the dish by the characters in TOS at all. It wasn't until TMP's novelization that Mr. Roddenberry weighed in on the refit Enterprise's dish as being a "navigational deflector", performing forward sweeps ahead of the ship to keep space debris and particles from colliding with the ship while in flight.
This notion of the ship relying on such a device to make flight practical seemed pretty dicey and implausible to me. Now, speculation into faster-than-light propulsion (the IXS Enterprise) suggests such a sweeping device may not be necessary. The proposed FTL drive stretches and compresses space around the vehicle; the vehicle itself barely moves while in flight. So if something did cross paths with the proposed IXS Enterprise, the ship's faster-than-light velocity would be irrelevant. Once the object crossed the warp threshold it would be inside the warp bubble, at a natural velocity.
Assuming this speculation holds up, the notion of a navigational deflector makes much less sense. Does this mean the STAR TREK dish would go back to being something else? Changing times would suggest the dish would have to, lest it become a dunsel.
