It appears that the gentleman thought C++ was extremely difficult and he was overjoyed that the machine was absorbing it; he understood that good C++ is difficult but the best C++ is well-nigh unintelligible.

I guess you could, but what would gain from it? You would already have processed the vertices, and if the triangle can be frustum culled then it will get clipped anyway before rasterization. If you're actually using tessellation to amplify geometry then it's definitely a win to set the tessellation factor to zero for patches that are back-facing or outside the frustum, since this will save you from having to do extra work in the tessellator and in the domain shader stage. But if you're not actually using the tessellation stages to tessellate, then there's not really any point.
