If dogfighting will never happen in the future, then all well and good.
Its not going to be the battle of Britain because it won't happen. In todays society we are that adverse to everything, that the very concept of dogfighting in the strategic sense will be avoided like the plague.
Hence from a strategic perspective, how much resources do you put into a platform that will have an small probababiltiy of doing it, or the game plan is to try an avoid it?
keeping in mind relative adversies and their size and tehnology gradients.
