What is the purpose of the Foglight group "Foglight Users"? (4260373)

When looking at the built-in groups on the "User Management" dashboard ,there is the group "Foglight Users". This group has no roles assigned but each Foglight user is member of this group.

It is not allowed to delete the group.

What is the purpose of this group?

This group could be considered as an empty envelope which can be filled by the Foglight Administrator.

As each Foglight user is member of this group, the group can be used to easily add or remove additional roles to all users. For example if you want to add the role "Report Manager" to all users, you only need to add it to the group "Foglight Users".

By default the group does not have any roles assigned and it cannot be deleted as it is a built-in group.
