Nice article! While reading I did wonder about a specific aspect:

This is also the reason why even a triangle that is just 1x1 pixels large still generates workload for 2x2 pixels.

Is a single pixel considered a triangle? Wouldn't that be just a vertex in computer graphics terms?

The pipeline is: vertex -> (triangle) -> pixel -> screen. Three individual vertices form a triangle, so even if that triangle ends up being just 1x1 pixels big, it's still a triangle.
