Not to veer off the OP's subject that I cannot logically address, but to counter some of the erroneous comments made here, I use four Canon L lens with Sony a6500 body and Sigma MC-11 adapter with no perceptible loss of functionality. I also have four Sony lens and they function very little or no better than my Canon lens on my Sony a6500. I've talked with others who have used both Metabones and Sigma Canon to Sony adapters and have observed that Metabones does not work as well as the Sigma. Prior to the release of the Sigma mc-11 I tried several other adapters and have not had the kind of experience with any adapter like I have the Sigma mc-11.

As a mere hobbyist I cannot justify a big "keeping up" expenditure each year to upgrade so I bought the Sony a6500 because it gave me features Canon didn't offer at the time plus the ability to use my Canon lens on it, even if I had to manually focus, features like in-body-image-stabilization for non-IS lens like my favorite wildlife lens, the ultra-lightweight Canon 400mm f/5.6L which lost autofocus with usage of the 1.4x teleconverter on my Canon FF body at that time. If my poor math serves me right, the a6500 effectively gives the 400mm lens image stabilization, an effective a f/1.4 to f/2.8 lens that will still autofocus on the a6500 with a Canon 1.4x teleconverter which, when combined with the 1.5x crop factor and Sony's 2x Clear Image Zoom gives my sharp 400mm lens a 1680mm field of view that autofocuses that I can handhold at a relative low shutter speed in a pinch with one stop loss of light for the teleconverter. Not only did I not lose any functionality, I gained a lot more and one of them is faster focus than with the Canon body even using Canon lens.
