There are scenarios where it would be good to have Project level reports like the users related to the People's section of a project. For example:

• Allowing to export a list of the project roles in use in a project and all the users that are currently on each role.
• Obtain all the users that have access to the project via Browse project permissions (which would in turn pull the users, groups and roles included in it). This would help project admins have a clear view and control of who has access to their projects.
• Generate a report of all project admins based on permissions.
• Add the ability to list the users added within the group of the People's section of the Project.
  For instance, if we add site-admins in the People section and grant them Service Desk Team role, we do NOT have a way to obtain the users who are part of site-admins
