And the question above is really talking about "signal an error"
(ie.. call just `signal' or `error') vs "the usual Tramp behaviour in
case of an error, where it tries to give you some more information in
case a connection does not work". This "usual Tramp behavior" is quite
problematic since it can't be silenced in the usual condition-case way.

Maybe the verbosity should be reduced by default. Or maybe it should be
provided differently: we could make it so that the top-level exception
handler (the one that outputs the message in the minibuffer if an error
is not otherwise caught) can be programmed, so Tramp could call `signal'
in the normal way and do the messy window-pop-up in the top-level
exception handler instead (so it doesn't do it if the error gets
caught).
That could save us from a `completion-only' kind of hack.

AFAIK they're in completion.el (a historical accident), simple.el (a
historical accident since most of the completion code was in C back
then), and minibuffer.el (which I couldn't call completion.el because
of the previous historical accient).

Yes.
