The bug report is dormant, so if we want to fix it, we should try the
proposed solutions and select one of them.

setopt-local didn't exist in Emacs 30, so I'm not sure what you tried
to reproduce there.

From where I stand, setopt-local is a relatively recent addition, and
it will take some time to adapt all of Emacs to its introduction.
That shouldn't delay Emacs 31.1.

Hmm... the recipe is not very detailed, but the first issue is indeed
new in Emacs 31.

Will do in a few days if no one picks up the gauntlet.
