Obviously, command-modes doesn't consider natively-compiled functions,
but even if it did, it sounds like the information is lost at some
point, even with loading *.el and *.elc files:

  (progn
    (load "help-mode.elc")
    (interactive-form 'help-view-source))
   => (interactive nil)

Shouldn't interactive-form return the 3rd element as well?

Andrea, can you please look at this?  This is about the Emacs 28
pretest, so it's quite urgent.  TIA.
