Modifications to new editions aren't a new thing. What's new is the way that concept interacts with DRM-protected streamable content. If the Forces of Order got their way and copyright was fully enforced, changes to a show released by streaming only would be a lot more permanent and in a way "more retroactive" than they are today. Maybe that's just a minor example of the much more general problem of archival presented by DRM, but maybe it's a little more sinister because there isn't any outward indication of the thing being a "new edition" like there is with a book (publishing info page) or a software release (version number). So a historian/archivist would need to go around perceptual-hashing the whole content to determine that there were actually two or more versions of that one episode of that one show.
