+
+        The current implementation is rudimentary and does not account
+        for any roles inside the guild.
+
+        A correct implementation would take account of roles and make
+        the correct groups on list_data:
+
+        For each channel in lazy_request['channels']:
+         - get all roles that have Read Messages on the channel:
+           - Also fetch their member counts, as it'll be important
+         - with the role list, order them like you normally would
+            (by their role priority)
+         - based on the channel's range's min and max and the ordered
+            role list, you can get the roles wanted for your list_data reply.
+         - make new groups ONLY when the role is hoisted.
