First, if they already have a PC port your point is moot. They would still need to make a controller version for the Xbox and PS5, but the switch can use both.
Secondly, some games are simply not released on consoles because it simply doesn’t translate well without a mouse, like RTS games, for example.
With the official reveal of the mouse mode for the Switch 2's controllers there is the potential for so many classic games to flood the console.
Imagine what it could do with graphical adventure games, RTS games, management sims, etc.
We already know CIV VII will use the mouse, and I just hope this is just the beginning for a whole range of traditionally non-console games to finally make it to the platform.

I can absolutely see it happen.
