It wouldn't hurt to reference the suppression section in the context of -Wall and -Wextra. However, -pedantic is special in my mind because it doesn't start with "-W," because it is a whole collection of warnings not otherwise addressed, and not all of its warnings can be suppressed. Therefore, referencing the suppression section would be good, but a disclaimer is warranted.
