Re: Restated: Any hope for an extender?

Even if you get the answer what, other than say o well its not going to happen, will you do with it? Are you going to make your own or push someone to make it for you?

It would make the extender larger for one (not an optical reason but).

One reason for the RF mount (detailed by Canon) lower lens distance to sensor distance and the larger flange - more complex designs and better designs possible (reason they can now make an f2 version of the 24-70mm lens). The design of the RF 70-200mm is such that the last lens element almost sits in the flange, so the angle of the cone of light must have steep angles (more than the earlier EF70-200 where the last element is some way forward of this, ergo the angle was less). This make any optical design for an extender harder.
