I have to disagree, if I have a lens like the RF 50mm 1.2, there will be occasions that I would want to shoot it at 1.2/1.4/1.8 and not 7 (that is why I paid for it), previously, to nail the eye, you had to take headshots as with a medium distance it would only do face tracking and it was super slow.
Checking the results on camera or with the evf will not tell you if it is perfectly in focus, for that you have to shoot tethered and depending on the location you may not have that option I have taken thousands of shots with the EOS R and I can tell you that on super bright apertures, the face tracking sucks and I had to rely 99% on single point af.
