Yeah, I'm betting Madonna had a doc planned all along and either shopped it to Netflix or they asked her to contribute to their new doc series where each new episode would feature a new artist.

i dont expect this is part of the bigger project but rather her taking control of a genre that has been focused on her lately, the Strike a Pose thing, the Emmys movie thing, etc

Gaga's documentary is a standalone film, I haven't heard about a "larger project" since they haven't announced anything. Netflix has a couple of documentary series about creators and/or creative processes ("Chef's Table" & "Abstract: The Art of Design"). Music documentaries don't belong to a series, the ones on Nina SImone and Keith Richards are the best.
