Somehow, I did miss the bug. I don't read all bug reports, and likely
the subject line was too long in order to get my attention with the
words "known hosts". So be it just now.

Well, time has passed, and Tramp has changed. Meanwhile, a method name
is mandatory.
I've tried with recent master (Emacs 29.0.50). If I call
emacs -Q -L ~/src/tramp/lisp/ -l tramp -f ido-mode
I can type "C-x d /ss TAB", and the method "ssh" is not offered. So I
continue with "h: TAB", and again, the host name is not offered.
If I read a file name, via "C-x C-f /ss TAB", it completes to "/ssh:"
(and the similar methods). Typing ": TAB" gives me host name
completion. So the situation is similar to what the OP has reported.
However, I don't know ido.el pretty good, so some body else, who knows
this beast, might continue with analysis. If there are questions from
Tramp, don't hesitate to ask.
Best regards, Michael.
