C-x C-q ; buttons donʼt disappear
(personally I donʼt mind the buttons, but the intent of faf1f037987c
was to make them disappear).
I came up with the following, but I can never remember all the details
of text property removal (maybe we need a `button-debuttonize-region'?)

Probably it would be the right thing to move this code to `button-mode'
to remove properties when it's disabled.

That would be best (assuming Iʼve got the incantation right ;-))

Although `button-mode' is described as a mode for button
*navigation*, so changing its behaviour might annoy people. Weʼll let the
maintainers decide that one ☺️

The change will fix its behaviour only for disabling with
(button-mode -1). I don't see how this might annoy people.
It's the standard thing for a mode to clean up after itself.

OK. Are we agreed that `unbuttonize-region' is a good name before I
update the manual?
(Hmm, `buttonize-region' isnʼt in the elisp manual. Iʼm assuming
emacs-30 is still open for documentation changes, if not I can fix
that on master.)

OK. Done.
Iʼve just remembered that button.el can use either overlays or text
properties to make buttons, so `unbuttonize-region' should look like
this:
(defun unbuttonize-region (start end)
"Remove all the buttons between START and END.
This removes both text-property and overlay based buttons."
(dolist (o (overlays-in start end))
(when (overlay-get o 'button)
(delete-overlay o)))
(with-silent-modifications
(remove-text-properties start end
(button--properties nil nil nil))
(add-face-text-property start end
'button nil)))
