Canon has patented an optical formula for an RF 200mm f/2L IS USM

EF 300/2.8 became RF 100-300/2.8, a zoom.
I wonder if EF 200/2 will become RF 70-200/2, a zoom.
70-200 f/2 would be a monster.
There is a patent for a 70-135 f/2.
Maybe a 200 f/2 prime would be all that is needed.
The rationale for the RF 100-300 f/2.8 being a zoom is that there is no advantage to an RF 300 vs an EF 300 due to the back focus length.
Making it a zoom gives a 100-300 a huge advantage over an SLR equivalent.
It makes the similarly priced Nikon 120-300 look like a hideous monster.
