Is it worth exploring whether we can add roles here in terms of visibility?

As part of our SOC2 compliance protocol, we are no longer giving Comms access to temporary XPs. Since a lot of our delegations require Comms, it might be helpful if there's a role for temporary XPs (and even independent contractors) if there is a role that only allows them to see threads that @'s them directly. They would not be able to see public threads unless they are directly mentioned.
