I think it's important to keep in mind that those of us doing these captures are doing it primarily for ourselves. OK so some of us are happy to share our finished projects with the wider fan community, that makes it fair game for constructive criticism regarding the quality of transfer, but you cannot criticise someone for their personal preferences.
If MeBe and Zion will be happier sitting down to watch their DVDs knowing that they have fixed some of the shots, then that's completely acceptable.
Personally, I fall into the DanielB "purist" category. I will limit my transfers to noise filtering only, I will not be fixing dodgy effects shots, creating a remastered 5.1 soundtrack or changing the Death Star scene so the stormtrooper no longer hits his head on the door
