No, I don't either. I don't have a big issue with reversing restoration.
I take issue with badly scraping books or destroying the edges to conceal trimming. If reversing restoration creates greater damage to the book, I'm not a fan.
I also think any work that has been done should be disclosed to potential buyers. If I'm spending 4, 5 or 6 figures on a book, I would want to know what's been done to it. That's what I think CGC should communicate, either with a label change or through graders notes.
I personally would buy a book like this superman. It presents beautifully. But I would want to know it was restored and that restoration was reversed.
Disclosure - I'm saying I would buy that superman hypothetical. As I heard so many times in high school, it's out of my league.
