Indeed. When I complete "/ssh:f TAB" with one of `emacs21', `emacs22' or
`basic' in `completion-styles', I see the call

(file-name-all-completions "ssh:f" "/")

which performs host name completion in Tramp. For the other completion
styles, there is just

(file-name-all-completions "ssh" "/") ;; for `partial-completion'

or

(file-name-all-completions "" "/") ;; for `substring' and `flex'

or even no call for `initials'. So I have added the following sentence
to the Tramp manual:

--8<---------------cut here---------------start------------->8---
User name and host name completion is activated only, if file name
completion has one of the styles ‘basic’, ‘emacs21’, or ‘emacs22’.
*Note (emacs)Completion Styles::.
--8<---------------cut here---------------end--------------->8---
