I wanted to say thank you for this thread, it is incredibly helpful!
For the first post. Sleeping Beauty’s 1997 Laserdisc is the digitally restored one with rotoscoping. The feature about rotoscoping all the characters out, is a feature on that laserdisc.
So the aggressive restoration it mentioned is from 1997, not 2003. Only the pre 97 versions would be purist, although they are Pan and Scan.
Did you read the first post?
“Snow White and the Seven Dwarfs (1937): First ‘fully restored’ by Lowry in 1994. This is also when the Masterpiece VHS and laserdiscs came out. As far as I am aware there is no home video format that has not been reanimated.”
The recommendation is for the least altered version available.
There is no purist recommendation.
