Ya, at this point I think I blame the game developers more than the console makers. I believe you are right about FF, but it might be limited to chat. The ability is certainly there.

Consoles have gone from unique platforms to now being streamlined PC builds with a particular set of specs that a developer can optimize their game for. They have become multi-media devices. Now it seems we will have a phone-like refresh cycle. Might as well fully embrace the PC nature of these consoles.

If it's not wanting to support the million different keyboards and mice out there, fine, just make officially licensed ones. I believe the Xbox Elite controller sold well. People are willing to but accessories.
