Using a non-extranet space shared by users from different extranets (e.g. for general information) adds a new use case to the Space Privacy app.
This configuration has been supported since version 1.2.0.
Extranet users inside a non-extranet space can not share a page with users or groups outside their extranet space.
The "User List", "Popular Labels" and "Recently Used Labels" macros do not show sensible data.
