In addition to Adam's well thought out points about project structure, I believe we still need access to
sanic.readthedocs.org in case we ever need to modify the webhooks for documentation. I don't mind using gitter for chat purposes, but someone would probably need administrative access to that as well if it's not directly tied to the org/repo administration. I believe the travis integration is tied to the org/repo so I don't think there's anything we need to do there.
I would also propose that we add a group for dev issues separate from governance issues that this group seems like it will be focused towards.
