We could, but is that really necessary? In general we try to avoid having UI elements dynamically show and hide themselves outside of the narrowly-defined exception of when a UI element is inapplicable to the currently active hardware. That condition doesn't apply here, so what we would do instead is enable and disable the button, which I think would be a bit weird.
