Others might not agree. See here: Any Errors in Definitive Edition? . If you wish to report the missing "Gifted" as an oversight, go ahead.
But by ArMDE and also TMRE as they are, troupes introducing "Gifted" familiars with RoP:M p.37 are welcome of course, but also completely on their own. Such beings are not meant to be supported as familiars in the current ArM rules, and questions about the status and role of weird familiars e. g. opened to the Hermetic Arts and/or initiated into TMRE Mystery Cults are completely left to the troupe.
