I agree. I just bought the r5 mirrorless. If you wantt the 1.6 crop factor for wildlife, guess what? You can set it up in the r5 and voila, a 200mm has the reach of 320mm. What you give up is pixels. Since it crops the sensor, your 45 mp sensor is reduced to around the equivalent of my 80d. Trying to decide if I should sell my 80D....
Canon is suppose to release a crop sensor mirrorless to replace the 90D this coming year. The Canon R7 should be out before the end of the year. I think that will probably be my second body if I ever sell my 5DIV. Like you I currently own an R5 but I am sure that the R7 will be pixel rich making it better for birding, personally I don't use the crop factor ability of the R5, I prefer to crop in post, also aids in clipping issues with long lenses when your subjects are fast moving.
