Canon Patent Application: Canon RF 35-135mm F2.8

This is a curious optical patent from Canon featuring some very uncommon focal length zooms.  Reading through the patent application, they simply seem to indicate they wanted to design a high-performance zoom.

A zoom covering 35 to 135mm however would replace a significant number of primes, would some of you like this lens?
