Minor mode keymaps work exactly this way (the minor-mode variable
enables/disables the corresponding keymap).  But usually it's not
necessary to disable a binding just because it's currently unusable.
Just like most menu items use :enable rather than :visible, since that
lets the user know that there is such a feature, even though it
currently can't be used.
