Enterprise resource management and allocation in Plan 5

I was on the phone with a Microsoft support person last week.  What he told me was that the resource allocation management is ONLY available in project online....NOT the new planner or premium planner.  It would be SUPER helpful if it read something like this "Enterprise resource management and allocation (Project Online Only)".  In fact, all features should read this way so we, as end users, know what we are getting and where it is available.  Just reading this looks like these features are all part of planner since that looks like the direction MS is going with all this.
