In the context of a private project, when I have a group and I add members to it, they are automatically added as project members and this is fine. Now, if I decide to bind this group (A) to another group (B), members of group B are not automatically added as project members. What happens is that they are silently part of group A, and will only be displayed when the users are added, manually as project members.
I feel like when I bind A to B, members of group B should be automatically added as project members.
