You may as well have said their positions are muddied because they also want more to do on tanks, not just healers.
That being said, the historical purpose of a "trinity" system has generally been to reduce the breadth of tasks expected of a player -- essentially replacing, say, a large portion of the actual efforts involved in "tanking" with merely being "a tank" (doing, for the most part, what a DPS does, but simply slapping a massive threat modifier atop that so that you're made a meat-shield by default). There is a tremendous difference between having more to do, as commonly asked for by those you consider as against the "holy trinity" and everyone being equally able to do everything.
