They’re just not officially supporting it. I hope Reto will informally make Metroid Prime 4 work with this the same way as MP1. I don’t like twin stick controls and mouse controls are not feasible on the go.
Even regular ass USB keyboards work with Switch. Usually not for control input but typing search terms in the e-Shop, for example.
