Hello, It would be better to ask such question on the user mailing list.
The reason is that the group is created automatically when a consumer joins it. It is not created explicitly so it can be restricted. In your case, you could setup a ACL to authorize the application to only use the group you have defined. It would prevent the application from creating new groups. (READ Acl on Group resource with a specific name).
