Thank you, but maybe silencing all warnings in the affected code was a cudgel 
heavier than the situation called for?
Perhaps something like this would do:

> (defmacro tramp--with-max-specpdl-size (new-limit &rest body)
>   (declare (indent 1))
>   (if (< emacs-major-version 29)
>       `(let ((max-specpdl-size ,new-limit)) . ,body)
>     `(progn . ,body))))

Or we could postpone the obsoletion for a while. The change was made partly for 
user convenience, but the typically package maintainer may not agree that this 
has been achieved: there is no way to be avoid warnings in code that has to 
work on previous Emacs versions without making it uglier.

Would it be a bad idea to, say, make a note to obsolete max-specpdl-size in 
Emacs 31?
