I don't think we need to wait until you bump the version to Emacs 29 to introduce this, as it doesn't specifically depend on `setopt'. In older versions, this will just have the same general limitations that defcustom :set had for aeons before Lars fixed this in Emacs 29: it won't fire unless you set the user option from `M-x customize' or use `customize-set-variable'.
