"User" in this case includes Lisp programmers; there's the "Lisp
changes" section in NEWS for that reason.

> Mentioning changed internals doesn't seem to be standard practice, but I could be wrong about that.

Text properties are not internals, they are visible to any Lisp
program and to the user.

Sorry, no, I won't.  I think this aspect of the change should be in
NEWS, and I'm asking you to document it there.  I don't understand why
I'm required to go to such lengths to justify a simple request.  If
you are still not convinced, I will do it myself, because this endless
dispute about a couple of sentences in NEWS is more than I can afford.

> The question is also whether it should be documented at all.

I think it should, and have said so.

Of course, I haven't seen them all, but having other people depending on implementation details of your software is a maintenance burden which either impedes progress.

Please leave the final judgment about that to me.  I understand your
point and your doubts, but I still think we should document this
aspect of the change in NEWS.  I hope this is enough to convince you.
