I agree on the issue with detaching body parts. I hated the sketch. It would be a bad influence for today's youth, and could cause kids to attempt it in real life and eventually get in trouble with the law. Kudos to HBO Max for editing out such segments. Ironically, the "Bert's Bust" sketch was uploaded by the official "Sesame Street" channel on YouTube seven years ago, and it is still there.
Same reason applies with the "I Wanna Hold Your Hand" song sketch. I hated it.
Ironically, I had no problem with "The Mysterious Nose Snatcher" sketch, which was quite short for a Bert and Ernie sketch, and it's not like we saw anybody remove a nose in action. Plus it was the only segment in which Ernie's nose was detached.
Off-topic, but on the topic of editing out, I did realize that segments involving Scanimate were likely edited out of Noggin broadcasts of older "Sesame Street" - with the exception of the Scanimate kids intro leading into a live-action insert, street scene or film segment. It's quite interesting that among the latest round of adding new episodes, I did discover two episodes with Scanimate segments: the one involving adding houses, and the Scanimate/live-action hybrid H segment - the latter of which was kept intact on the Old School DVD release of a season premiere (Season 9, perhaps?). Maybe this is an indicator that the Scanimate Films segments for the numbers four and ten will appear on future episode additions.
Aside from the remaining snow arc episodes from the 1970s, there is also an episode from Season 18 added as well - one that had only a very small number of segments on YouTube for a while, including "Water, Wind and Sun".
