I've seen questions about this a couple places, so I want to submit this as an idea. I have several employees who who create articles. For now I must give them the moderator role. Since this role is part of the team, I would overexceeded my number of team members.
Having the ability to assign an author role to anyone who just needs to create articles would be a huge improvement. For businesses with active employees, a limit of five team members (additional members cost additional money) is not sufficient.
