Well I think that u can use ML current models in a pro. level but you would want few cameras that do the same thing that way you ..have control over your production it really matters on what type of work your doing like weddings would work only for some of the footage but if you were to do music videos or short film you can control your actors and scene etc. i see all type of videos with ml from car to anything .so much out there just do a search on different plat forms and ideas well come .plus the footage from raw is beast even if it is 239:1 1736x726 like from t5i 700d with a experimental build https://builds.magiclantern.fm/experiments.html or eos m with danne build you can get 2k raw upscale to 4k in post ..you have to start playing with current models and new build will come in time . plus i think dual digic will take much longer development than single and more people have other models 7d mark2 is a sports photographer camera the more specialized camera the less development numbers game !
