Can't agree with this sentiment. I think Rockstar allowing the Xbox disc to pass for the 360 devalues the original game and goes against the core tenants of preservation purists. It's not full upfront and it really does rub me the wrong way as well.
Preservation purists play on OG hardware. There are all kinds of things that are inauthentic about playing OG Xbox games on X1 and even on 360. Conker's fur shader doesn't look right in anything over 480p, as one example. Lots of these games look more authentic on CRT than on flat panel and so on.
