I know someone has asked for category to be added and you mentioned making a custom page template for that. However, I think the need is still there, at least in regards to memberships.
For instance, I would love to have my site only show certain nav items to folks within a certain membership. Since we can’t specify which wp capabilities to give new users from a membership standpoint, this is the next best thing as we would then be able to hide elements based on a body class.
