IIRC, the F-16 is neutrally stable throughout much of its flight envelope. The main advantage for having a neutrally stable or unstable fighter aircraft is agility, quickness in manueverability. >And the FCS doesn't have to be too terribly complicated.

It includes little things like gun compensation. There are structural filters, scheduled filters, etc. It's not unsophisticated.
