Michael's post is hard to argue with. I just wish there was an easier way to reap the core benefit of a benchmark color space. Behind all the acronyms there is a very real upside to being able to take a wide variety of sources and put them in a reference container with fixed values for post/DI.
If VFX were not a part of the scene then roll your own LUTs might be sufficient, but that's not most people's reality. I also think that whatever dire warnings about digital and archiving you might place credence in, having an open source standard with wide parameters will improve the odds of being able to access digitally acquired images in the future.
