Federation IDs as 1st class users

[kaffeeringe]

Is your feature request related to a problem? Please describe.
Imagine everybody you work with on a project has their own nextcloud and their own federation ID. At the moment, if I want to cooperate with them on my project I have to give them a local account for them to be able to use all my project ressources (files, calendar, contacts, deck, collectives..."

Describe the solution you'd like
It should be possible to add a federation ID to a team and thus give the external user access to all my local project ressources.

Describe alternatives you've considered
I can share files with them and calendars and I can invite them to a chat. But that is extra work and they are not really in my team. If they leave the project I have to remember, where I have to delete shares with them.

• Federated Sync circles#1034
  I did see a working demo of federation across arbitrary data from Deck app through a federated Circle across three servers. That was a couple years ago, but my guess is it is not priority internally. Also probably technical concerns once you scale such a thing across millions of users. I do agree that it is the future. :)

• Mirror federated storage locally [$20] #8459
• API or protocol to migrate/import/export users [$70] #11653
  since these relates to the basic steps of migrating files, folders and users across federated servers. These feel like solid early goals towards the larger federation milestones.
