In that regard, those drivers exist, the PS4 for example already recognizes keyboards and mouse and you can navigate the UI with it, I think Xbox might be the same.
Also, games already play with these settings, games like Fortnite and CoD: WarZone do support KB/M combo natively, allowing you to play with either, even some other games like Border Break (A Japanese exclusive game) allows you to play with controller + Mouse (The way it was played in Arcades)
Right now, the situation with PCs is really bad, I would like to move back to PC but with some of the prices in the components I straight up say, no, it's not time at this point to think about something like that, and as many people says, on PC, you can use controller or KB/M, why not on console also?
Is honestly the only game I play out of the 3, but I honestly started to dislike the movement of the analog stick for camera controls particularly, and characters like Valk felt awful before I actually had to make my own controller customization (at least, something that I appreaciate).
There is, at this point and time, no excuses to not inclulde this mode, the game already includes crossplay and everything, so at this point 3 out of the 4 platforms the game can be played on, are on a disadvantage.
