Thanks, I added the caveat to these NEWS entries.

That's a 75-line node, so "in the middle" is also "close to the
beginning". In fact, it mentions it immediately after explaining the
issue and saying that Emacs has a mechanism for tagging commands as
being specific to modes. I don't see how this could be moved earlier
without severely disrupting the text didactically.

I don't think so, but I now tried to make it even more evident.

I've added the reference to execute-extended-command-for-buffer and
its binding.
