Are you saying lenses designed in the digital era that fit Canon EOS film cameras are off limits because they were made for digital cameras? That seems a fundamentalist stance even for this forum.
Digital photography changed design optimizarion rules. For example today more image distortion can be allowed if this is useful to correct better other features, as distorion is easily corrected digitally. Also color fringes are easily corrected by using slightly different distortion corrections maps for each channel, so spheric correction can be better priorized. Still lateral Color aberration cannot be easily corrected separately than longitudial one. Also it happens with secondary color aberration (green-magenta fringes).
Lens manufacturing technology has made substantial leaps forward that are only found in digital lens, in special if we focus on quality-cost ratio, in the past extraordinary lenses could be done but same performance level is today way cheaper.
In the high end product range we have seen substantial design change in pro zooms. In the past that VR 2.8 pro glass tended to be Parfocal design, today those zooms are Varifocal type, making a lighter, cheaper (manufacturing) an better desing, with one intrinsic flaw: "focus breathing", but electronics solve that, as we move focus the zoom position is servocontroled to hold magnification in place.
Yes... digital photography evolution made lenses better for digital, but not always this is good for film, if distortion is higher...
Anyway what is better is about personal preferences, to me a near century old 36cm Universal Heliar is better, I would sell all VRs I could have to pay one of those . Well, preferences are about the kind of sickness one may have
