@TankerFlankerdisability or not, it doesn't matter. Accessibilty may be also important to me, but in the end any game is a piece of software and the more input devices are supported the better for all players! The platform doesn't matter, except it doesn't support USB and the drivers - which consoles do since PS4/XB1 or even before that.
And those "specific needs", like you called them, well, without them we will still see specific game genres being excluded from consoles or being inefficiently to control. E.g. tell me a single RTS game which has been launched on PlayStation. Hard to remember? Yeah, I understand, because there wasn't any!
Even turn-based strategy is stripped down to gamepad controls like Civilization or Age of Wonders, only because those urban gaming legends of gate-keeping say "MnK aren't welcome on consoles" - I still remember C&C1 on PS1 with a mouse, but yeah... same goes for isometric RPGs like Pathfinder, Diablo or Pillars of Eternity 1+2. I bet Tyranny wasn't launched on consoles because of this issue.
But hey, you have high capable consoles, that could easily run the newest Company of Heroes, even Total War on medium settings, naah, rather buy a +1-1.5k PC to run those games, because consoles aren't shipped with devices worth 20-30 bucks, eeehm, YEAH...
I wonder how VR fits into this narrative. Can't remember finding this gadget in the PlayStation box too, even though the games are out there...
And to answer you about my attitude towards missing MnK support on games:
I've been playing on consoles for several years now, also Battlefield! I got used to the gamepad controls after months of tweaking and practice, which works fine except on planes.
But I also play CoD with MnK since Modern Warfare introduced it and mixed lobbies are always balanced to me. More balanced than Battlefield has ever been on consoles since BF1, because of the massive skill gap - which will be increased even more due to Crossplay with PC. So yeah, I wanna enjoy Battlefield the same way I do in CoD. Balanced and efficiently to play as same as anyone on PC. And CoD shows pretty awesome that there is not issue at all when it comes to balance. Battlefield just needs proper balance tools for servers rules, teambalance and matchmaking.
