Just to go into it a bit more as I maybe didnt clarify it best in prior comment.
No single person will do all of the specific type of work, because the work load would be extremely high. So for example, wer all doing outreach for certain things. Crim does outreach for stuff she does. I do outreach for things i do. GP does it. Crim talks to exchanges. Ill be talking to exchanges in regards to a specific project here. GP will talk to some conferences, ill talk to others. Crim will go to some conferences, im going now to one. So its kinda who can grab what.
When I say that the structure you hint at is not possible, its precisely because there is no pay and its not a real job. Its voluntary work thats extremely wide in scope, with an extremely limited number of people doing it, and no one can be asked (required) to do anything that they do not volunteer for. They will try their best to do so if asked, though.
Time available and burnout is a real thing and beyond trying to cover all the needs this chain has, maintaining burnout is a must. So you simply cannot allocate work in a way that would be optimal. That is the structure im talking about. And again because of this, I can only speak for how I see things. I cannot guarantee others share my view.
