I'll give it a try.

As you may know, the original Leicaflex had an external meter.  Therefore,
only the aperture that the lens was set to needed to be communicated to the
camera body.  This required one cam.
When the SL (and SL/2) came along, they provided TTL metering at full
aperture.  This required a second cam to let the camera know the maximum
aperture of the lens being used.

When the R3 came along, it was based on a different system (Minolta?).  This
added the third cam.

I own both the SL and SL/2 and couldn't imagine giving them up.
