Hmm, there was an error in the snipptet. I've reworked it, and added to
the Tramp manual (pushed to master):

4.18.1 Using ssh config include for host name completion
--------------------------------------------------------

OpenSSH configuration files can use an ‘Include’ option for further
configuration files.  Default TRAMP host name completion ignores this
option.  However, you can configure this yourself.

   Given, your ‘~/.ssh/config’ file contains the following option:

     Include ~/.ssh/conf.d/*

   The following code snippet in your ‘.emacs’ uses all files in that
directory for host name completion:

     (tramp-set-completion-function
      "ssh" (append (tramp-get-completion-function "ssh")
                    (mapcar (lambda (file) `(tramp-parse-sconfig ,file))
                            (directory-files
                             "~/.ssh/conf.d/"
                             'full directory-files-no-dot-files-regexp))))

   This code snippet does it for the ‘ssh’ method.  If you replace
"ssh" by "scp", it does it also for that method (or any other method
you like).
