Keyboard and Mouse support on consoles

Since the generation of PlayStation 4 and Xbox One consoles, games can have keyboard and mouse support. it could be useful in CO-OP and Vs. modes on consoles, if the people only have one controller but have a mouse, or just want to play with a mouse on the console, because console graphics are generally better and some people are already used to play with mouse so they don't want to use a controller. You already have the code for mouse support because of the PC version, so why not port this code to consoles? It would be nice...
