Some images require hours of painstaking editing. There are some photographers who will spend
days or more editing an image. The edited image is as much an instantaneous snapshot of the photographer as it is the scene in front of the lens. Looking at my Darktable catalog, it is easy to estimate that I spend at least 250 hr/yr editing images.
Raw files, and sidecars, retain their value because sometimes one wishes to revisit an image/edit. If I had to pick one or the other, I might prefer to lose the edited images. That is because I believe I have more/better days of my editing life ahead of me and because I underestimate how much editing I have done. Moreover, there are plenty of RAW images awaiting the day they come to life.
In commercial work, like weddings, the final product is the edit. If there is one thing that must be retained, that is it.
