Beards are definitely more of a leap than de-aging as funny as that seems, this stuff still isn’t quite magic yet. At the same time I wouldn’t find it all that worth it for any of the characters to sport a beard for the sake of it, maybe I’m missing something but I don’t see what it adds other than a tracking continuity nightmare.
(Would be kind of funny if some characters went between bearded and clean faced to establish regular shaving habits within the canon…)
