It turns out, that Emacs has already the sufficient machinery. I have
added the following lines to the Tramp manual:

--8<---------------cut here---------------start------------->8---
   TRAMP warnings are displayed in the ‘*Warnings*’ buffer, which pops
up.  If you don't want to see this buffer for every TRAMP warning, set
‘warning-suppress-types’:

     (setq warning-suppress-types '((tramp)))
--8<---------------cut here---------------end--------------->8---

That's it. Pushed to the emacs-30 branch. Closing the bug.

Best regards, Michael.
