[~adam-mesos] does this being labelled {{mesosphere}} mean this is on your 
roadmap in the near to medium term?

> https://issues.apache.org/jira/browse/MESOS-1219 disallows completed 
> frameworks from re-registering with the same framework id, as long as the 
> master doesn't failover.
> This ticket tracks the work for it work across the master failover using 
> registrar.
> There are some open questions that need to be addressed:
> --> Should registry contain framework ids only framework infos.
>     For disallowing completed frameworks from re-registering, persisting     
>     framework ids is enough. But, if in the future, we want to disallow
>     frameworks from re-registering if some parts of framework info
>     changed then we need to persist the info too.
> --> How to update the framework info.
>       Currently frameworks are allowed to update framework info while re-
>       registering, but it only takes effect on the master when the master 
> fails 
>       over and on the slave when the slave fails over. How should things 
>        change when persist framework info?
