I not 100% certain, since I don't have an iOS device to hand, but that was the impression that I got from talking to Apple engineers. If it's not, then it's something else providing exactly the same programatic interface and fulfilling the same function, and I'd be very surprised if Apple did that, although it's possible that they moved the code into the running GUI process for efficiency, since every app runs full-screen. In that case, the windowserver binary would just be a dylib that everything linked to, rather than a separate app (but would still be the same code).
The window server is a completely different binary (it's the PurpleEventServer), but it's still Quartz and CoreGraphics backed.
