Preservations don’t turn a blind eye to goofs, rather they’re lauded. “Warts and all” is the nuts and bolts of a good preservation, once you start fixing things it quickly turns revisionist. It isn’t at all that preservation should be redefined, but that you need to find the correct words to describe what you want.
Perhaps yes, there could be a perfect version that could come from fixing things that weren’t intended to end up the way they did, but that’s a moving target which cannot be reached and satisfy all people. Any way you go about it, though, it is outside of the scope of a project like this.
