Can anyone explain why the R100 can't use the RF extenders?

Can somebody please explain why the patents often include the 'L' designation of the lens? I mean, the 'L' mark is rather a marketing...
Richard CR replied to the thread Canon Teases Us with a Canon RF 35mm f/1.2L.
the embodiments are not usually drawn to scale at all so I presume there's just less empty space. I was a little surprised by the lens...
