-* While suggestions for new features are welcome, it's important to
-limit the scope of NetBox's feature set to avoid feature creep. For
-example, the following features would be firmly out of scope for NetBox:
-
-    * Ticket management
-    * Network state monitoring
-    * Acting as a DNS server
-    * Acting as an authentication server

+accepting any proposals which substantially extend NetBox's functionality
+beyond its current feature set. This includes the introduction of any new views
+or models which have not already been proposed in an existing feature request.
 
 * Before filing a new feature request, consider raising your idea on the
-mailing list first. Feedback you receive there will help validate and
-shape the proposed feature before filing a formal issue.
