So something like

    (defcustom project-list-exclude nil
      "List of regexps and predicates for project root and objects to exclude."
      :type '(repeat (choice regexp function))
      :version "31.1"
      :group 'project)

as we cannot remove your advice if we don't pass the project object to
the predicate.

BTW, would it be too late to check this user option in
project--write-project-list, or should we check this in
project-remember-project as in your advice?  IIUC, the former would more
closely resemble recentf's behaviour.
