It would certainly be an interesting document, but I suspect you’ll get a bit of the old “ask 3 lawyers and get 5 opinions” kind of response. ;)

As I remember it, there was definitely a feeling like, this would be our only chance to clean up some annoying cruft, and rectify some (in hindsight) incorrect design decisions made over the years, couple with a healthy dose of “we have no idea how to do the bytes/str split in a backward compatible way".  There was probably a sense that the Python community was just small enough to be able to handle such a disruptive change, but wouldn’t ever be so again.  The latter is definitely true today, even if the former was overly optimistic.
