The point is that this is some external data, obtained at run-time from files that are not necessarily under the control of the program (eg. some distributions package the localisable file separately).

Therefore if you insist on avoiding “%s” you should, to keep the program correct and secure, do the following:

     fprint(stderr,escape_print_directives(GETTEXTL(“Warning: “)));

and suddenly, using “%s” looks way simpler.
