Andrew, the main issue we have is that one person's "right" is another person's "wrong". This is one of the reasons why we provide multiple profiles, and tools for users to make/edit their own profiles. Most of our "Camera Matching" profiles that we provide are actually less accurate in my personal testing, but many users like them. For a specific example: Some users prefer stronger tone curves (e.g., for Canon, Camera Standard, Landscape, Portrait) and other users prefer gentler tone curves (e.g., for Canon, Camera Neutral, Faithful). For Adobe Standard (1 profile), there is just 1 tone curve, so it can't be both strong and gentle at the same time. We chose to make it on the stronger side (more contrasty), but this doesn't appeal to folks who prefer a gentler curve.
