Thinking about this a bit more:

* `/roles` currently doesn't show quotas.
* It also doesn't show dynamically reserved resources.
* If you set ACLs that involve a role, you could argue that it should show up 
in `/roles` as well.

Given that most of these issues are not related to implicit roles as such, I'm 
inclined to say we should defer making these changes -- perhaps as part of the 
work on dynamic weights/ACLs, we can reorganize the data structures to make 
this easier to implement anyway. I created 
https://issues.apache.org/jira/browse/MESOS-4097 to track this.
