Is there any interest in listing a bicycle's components for documentation purposes?

I noticed (while following the KHS Team Pro bicycle thread) that many times, when someone ends up finding a bicycle, the new owner doesn't have a clue if the components on his new purchase are original. I don't consider myself a "factory completest" when I consider my own rider bicycles, but I am always sorta curious to what appeared on the bicycle to begin with. Is there any benefit or interest in possibly documenting that type of information? I realize for some bicycles there were catalogs made, and for popular brands these have been shared to the interwebs, but for something like the KHS Team Pro, catalog data seems pretty scarce. And have you looked at bicycle catalog listing on #bay lately (I horded the wrong things, apparently). Well, let me know your take on the subject, and thanks in advance.
