So no TV-MA possibility then. Great news!
Disney has a policy of not allowing anything above PG-13/TV-14 on Disney+. Any future R/TV-MA content from Disney, such as the rumored continuations of the cancelled Marvel-Netflix shows (Daredevil, etc.), will go on Hulu instead of Disney+, as Disney now owns a majority 67% share of Hulu. Disney wants to keep Disney+ family friendly.
