Hi,

This is due to a changed behavior of `unload-feature'. Prior this patch,
there is

--8<---------------cut here---------------start------------->8---
# emacs -Q -l tramp
(unload-feature 'tramp 'force)
(mapatoms
 (lambda (x)
   (and (functionp x)
	(string-match-p "^tramp" (symbol-name x))
        (message "%s" x))))
=>
tramp-register-archive-file-name-handler
tramp-archive-autoload-file-name-handler
--8<---------------cut here---------------end--------------->8---

This is OK, because tramp-archive.el is not unloaded via unloading
tramp.el.

Now, this behavior has changed. With the same recipe, we get

--8<---------------cut here---------------start------------->8---
=>
tramp-unload-file-name-handlers
tramp-unload-tramp
tramp-register-archive-file-name-handler
tramp-archive-autoload-file-name-handler
tramp-register-autoload-file-name-handlers
tramp-autoload-file-name-handler
--8<---------------cut here---------------end--------------->8---

Best regards, Michael.
