The reason for putting toggle-read-only into that list is that it
displays a message, and programmers who don't know better would often
use it for code that wants to modify some read-only text, code that
really ought to bind inhibit-read-only.

    There are lots of toggle-read-only warnings in the Emacs Lisp source

How many is "lots"?

      As far as I can tell, the overwhelming majority of these are all
    legitimate use cases.

That may be true -- because most of the erroneous uses were already
fixed thanks to this warning.
