tramp-set-completion-function is used for host name completion only. It
doesn't change anything how Tramp calls ssh.

If you want your "~/.config/ssh/config.d/config.whatevs" file to be used
for the ssh connection, you might create a small file "~/.ssh/config"
with the contents

--8<---------------cut here---------------start------------->8---
Include ~/.config/ssh/config.d/config.whatevs
--8<---------------cut here---------------end--------------->8---

See (info "(tramp) Ssh setup")

Alternatively, you could add an own method to `tramp-methods' which adds
the "-F ~/.config/ssh/config.d/config.whatevs" option to the ssh call.
