Windows 10 had a tablet mode. Windows 11 does not - it just appropriately scales up the padding and size of some UI controls to make them easier to tap.
The introduction of the mouse led to developers paying less attention to keyboard shortcuts and function keys, but I don’t see anyone seriously saying computers should not have mice.
Or for that matter, that adding support for game controllers (something that has actually happened with Linux desktops) would led to curtailed development of non-controller parts.
