Thanks to everyone who responded here.
I am a qualified no.
I think there are parts of the Fediverse that can benefit from coordination, like how the SocialCG coordinates work on ActivityPub and Activity Streams 2.0, how IFTAS coordinates trust and safety work, and how Fedipact coordinates blocking Threads.
@evan missed the poll but my answer is there should not be an organization to govern the fediverse; there should however be at least one organization to enable many forms of governance in the fediverse
