Well, that would cripple MOL considerably. A lot of MacOS applications (admittedly most of these are games) expect to be able to change the resolution or the depth. But the really imporant reason is that in order to allow switching between MOL-in-a-window and console video (which is much faster), several resolutions must be supported since running MOL in a X-window with the same size as the screen is not very useful. The main problem is that MacOS wants to know all the details about the available video modes at startup. This information is also necessary in order to make a transition possible from X to the console. Thus, if the API is going to change, I would really like to see a possibility to obtain both the var and the fix information for any supported video mode.
