By definition, every Component in an Assembly is a 'Master Model', in that the Assembly is simply of collection of pointers back to the original 'Master' part files where the Component's geometry was defined. As 'Master Model' Drawing is simply a specialized 'Assembly'.
BTW, you can also use PMI in a 'Master Model' mode in that you don't have to be in the same part file as the geometry to assign PMI dimensions and annotation including GD&T. Master Model is also supported with CAM and CAE operations. In fact, CAE enforces the Master Model approach even when used in native mode without Teamcenter being in the picture.
And while I agree that over time the expanded use of PMI, applied to the actual model geometry and/or its features, will reduce the need for, and eventually the actual creation of, traditional fully dimensioned, annotated, multi-orthographic-view based Drawings, it will be years before this is the norm and so until then, the most effective use of Drawings will still be as separate documents which reference, but does not actually contain, the part model's geometry.
