One imagines that the stick-shaker might also operate (there is no stall alert-tone or warning-lamp). Depends how close to the stall this stall-trimmer system starts to operate. Other than that, I presume the new system is like the STS, and all you get is the clunking and clanking of the trim-wheel. If it had a new warning tone or light, it would have needed a separate section in the manual.
And bearing in mind that this was a spurious warning, would the stick shaker even operate..?
