OK, attached is a draft patch to emacs-27. Although it doesn't go as far as your
patch, it does keep some of it, and in particular it gets rid of the
introduction of the term "constant" to describe objects that should not be
changed. It also omits the "Dangerous" that Drew objected to, and gives an
example of a term that was formerly mutable but is now something that you should
not change.
