If you constantly die, more stam helps. If you're at a point where, at no time in progression are you at risk to die, then you've gotten to the point where more stam effectively does nothing. Of course, if adding more stam allows you to change raid comp (ie, one less healer), and such a thing is possible, then more stam can be more effective, as long as the added dps adds more to the raid dps than you switching to stacking, i.e., haste.
And looking at what the cutting edge progression raiders do doesn't mean much - they're pushing content in lower gear than it's designed around, so stack stam to make up for the fact their gear doesn't have that additional stam by default. That's not to say additional stam above what comes on gear isn't needed, but that you have to look at the reason for why they stack stam, rather than just the fact that they do.
