I have heard that the current Switch already supports mice, but very few games use it, since no one has a mouse connected to their Switch, since almost no games use it. If there is an (uncomfortable) mouse included in every Switch 2, game devs will be more willing to include mouse controls in their games. Players who play a lot of mouse enabled games will hook up a real mouse to their system. Much in the same way that every game for the current Switch supports Joycon controls even though many hobbyist gamers will use a more traditional controller.
