This is one thing that I think YouTube gets right. Once a video has been posted and comments have been posted, liked, etc, you cannot change that video in any form. This is on the premise of avoid bait-n-switch to put of a video to garner the positive response and then swapping it out with a different video. Amazon should do something similar.

I don't thunk that would work with physical objects very well. Especially when recalls are done via serial number. Apparent identical physical objects are always fundamentally different from each other unlike data.

It's a lot harder. Google makes all the copies of a video. Amazon doesn't make all the copies of a product.
