I'm actually going to try my hand at a controlled experiment. I have several different cameras that I want to check to find out whether detail in the iris is actually possible with small sensor cameras at all, or if diffraction will destroy all detail before it ever reaches the sensor.

You can pretty much rely on crop factors to determine when diffraction will have a visible effect, assuming a particular final image size and viewing distance.

For example, f/2.8 with a 1/2.3" sensor (5.6x crop factor) corresponds to f/16 with 35mm, which is widely considered a threshold of diffraction territory for typical viewing situations.
