> The AccessController allows users to store cells with ACL tags encoded by the
> client. This isn't a security issue currently, because in order to store the
> cell the user must have a relevant WRITE grant, and the user is allowed to
> specify whatever ACL for the cell they'd like. However it could become a
> correctness problem in the future, if we introduce format sanity checking or
> the like, so let's disallow inbound mutations containing cells with reserved
> tags like the VisibilityController does.
> The check is skipped if the active user is a superuser. First, superusers are
> allowed to do anything. Second, replication (as superuser) must be able to
> store incoming cells with ACL tags.
