Mesos frameworks and roles

[yuliya Feldman]

Hello here,
This question is really for Mesos guys :).
"roles" and frameworks in Mesos. As far as I understand today each Mesos 
framework can be associated with a role and subsequently mesos-slave can 
allocate shares of resources per role.
Is it still the case? Meaning we still have no more then one role associated 
with a framework.
Thanks
