I was responding to Lars, not to your original request.

Yes, yes, everyone knows that.  No need to reiterate the trivia.
Please focus on the real issues at hand.

Yes, we understood that.  No need to reiterate.

Please re-read what I responded.  Which part of it contradicts what
you requested?

The UI effect of 'message' can be easily disabled by the Lisp program
which calls 'message', which in effect converts 'message' into a
logging function.  Include that in the code that calls
'minibuffer-message', and you have what you wanted, no?

Please don't second-guess my misunderstandings.  It is rude, to say
the least.

You are already able to do that, AFAICT.
