Federated Groups are quite challenging to get right.

I'm discussing our impl with @trwnh and there are several aspects and side effects that no other implementation has approached, including:

- Private groups
- Group roles
- Group moderation
- Group fallback delivery
- Group migration
- Group mod logs
- Group admin vs Instance admin ownership

Everyone wants groups, which is understandable.

Nobody wants admins to be able to takeover groups, like Reddit did.

@pixelfed will get Groups right 😉
