Entering the lens data manually is certainly possible as I do this regularly 
on my Nikon D200. I don't think that the camera does anything with the info, 
though, except enter it into the EXIF data and probably use it in the 
metering programs.All that is entered is the focal length and maximum 
aperture of the lens, and that value is then stored for future use. You can 
have up to 4 different  lens max. apertures for the same focal length using 
custom menus.

I see no reason that Leica could not have stored a list of the lenses 
supported by in-camera processing in a menu for easy selection, though lens 
"upgrading" probably does supply a small but significant (to Leica) revenue 
stream.

As an aside, it is pretty amazing to use an EXIF viewer (like Opanda for the 
PC or EXIF Viewer for the Mac) to look at all the data that is recorded for 
each shot taken with a camera- there is far more recorded than you see with 
most image viewers. I just learned that the total number of photos taken 
with the camera is recorded in the jpeg files, along with a lot of other 
esoteric, equally useless trivia, though it might be useful if you were 
buying a used camera.
