`setopt' does not really help. Using `customize-save-variable' instead
of `customize-set-variable' does the trick.

Pushed to the emacs-29 branch, closing the bug. Pls reply if it doesn't
work as expected.

Best regards, Michael.

Apologies for an incomplete bug report.  Feel free to close if not
helpful.

I downloaded the Windows binary posted today, with dependencies
included, and gave it a naive try using my setup.  Naturally I ran into
some problems.  But when I went to exit, my `kill-emacs-query-functions'
code that checks for changes to user option values (using function
`customize-unsaved') let me know that something had changed these option
values (I had not changed them):

connection-local-criteria-alist

Its value is

(((:application tramp)
  tramp-connection-local-default-system-profile tramp-connection-local-default-shell-profile))

Original value was nil


connection-local-profile-alist

The value is a long, complex Tramp alist.  Original value was nil.

So it looks like Tramp (?) might be messing with user-ooption values,
without resetting their state to tell Customize that they haven't been
changed since last saved.  This should be a no-no.

HTH.
