Aha.  One idea would be for tramp-compat to including something like:

    ;; Remove when Emacs >=31 is required
    (require 'loaddefs-gen)
    (cl-symbol-macrolet
        ((amac (alist-get 'autoload-macro macro-declarations-alist)))
      (unless amac (setq amac #'ignore)))   

to silence the warning, yet remain harmless once Emacs 31 is in the
wild.
