I can't see how adding this functionality would hinder anyone's workflow
It wouldn't necessarily, but it does take resources, which aren't unlimited.
Mind you we're not talking about tweaks here. If a camera goes wonky and I change over a few frames late, that's very quickly and easily corrected by sliding the cut point over with the Rolling Edit tool. Here were talking only about the need to add a new cut point and change the camera angle for the new cut. If you have to make hundreds of those changes after the first draft in the multicam window, then you need a LOT more practice with multicamera cutting. Not making that many mistakes will speed up your work flow a lot more than this feature request will.
