I do consider the non-anamorphic format to be a bug. Why? Because industry standard at the time was to release widescreen movies anamorphically. It shouldn't have been necessary to state that it was anamorphic; a reasonable presumption is that it would be. It's also the first thing that fan edits correct when using GOUT as a base - something LFL should have done from the start. So it is obviously for all practical purposes a bug that should have, and could at zero cost have been, fixed.
If a DVD of Wizard of Oz came out and it turned out to be black and white, would it not be a mistake because the label didn't say "in color"? No, certain things are just presumed. If it skips, would it not be a mistake because the disk didn't say "won't skip"?
Perhaps if the disc included the label - "disclaimer: outdated crappy non-anamorphic f-ed up transfer", then there wouldn't be any bugs!
