Developing a raw (not an acronym) into some wide gamut space and applying whatever transitions at that point is still fine.

This isn't just "fine", it's essentially the only sane thing to do. That intermediate space ought to be "linear light" so that operations like resize or blur work properly. This is the only mode in which Lightroom operates. There's basically no other way of using it. It's not only not the default in video editing tools, it's decidedly non-standard and you have to go out of your way to enable it. Then everything breaks because the tools still have too many baked-in assumptions that you're operating in the output space or some other non-linear space. In a tutorial video one professional Hollywood colorist said something like: "This color space has a gamma curve of blah-blah-blah, which means that the offset control will apply an exposure compensation." That blew my mind: edit controls that change behaviour based on the input and output formats to the point that "addition" becomes "multiplication"!!

  Sure. So back to your previous point, when you develop the source CinemaDNG footage you do not deal with any transitions, are not cutting it, and do not need it to be real-time. It is simply a bunch of stills, which you process into a straightforward sequence of pre-graded PNGs in your desired colour space that you are free to edit together however you like at blazing fast speeds. Unless you go crazy on some very specific transitions (and who uses transitions anyway in film these days) that don’t work in final colour space, you do not need raw footage at edit time, do you? I guess I know the answer, if you work in this industry then punching in/out or stabilizing in post is a common requirement and you mentioned some tools can mess up even at resizing stage.

    I’m not a professional, I just “dabble”. Something I’ve noticed in fields where I am a professional is that it’s the “WTFs per hour” from intelligent beginners that best measures how broken some ecosystem is. Video editing is very high on the WTF/hr metric.

      Then try workflow I described. Too cumbersome and exotic for a pro, somewhat clumsy or nonexistent GUIs, but almost entirely open-source and very few WTFs.

  Addition becoming multiplication is simply the difference between linear and gamma encoded space. Gamma curves are mostly log based since it maximizes bit usage in formats, and given 2 linear colors A,B, and an addition operator, applying it in gamma space is logA + logB = log(A*B).
