>more irregular in size than wheat berries

Wheat is one of those plants that humans have mastered. One person can farm thousands of acres of wheat. Generally that's only true of plants that are very uniform and that you wipe out each harvest. It would be very hard to replace it with a plant you can't use the same techniques on as the labor would be 100x probably.

We're on the cusp of an era with an embarrassment of labour, however. This sort of crop might not be useful yet, but heterogeny is going to be a theme when gains to date in informatics and robotics begin to be reflected in mature agricultural technologies.

Kernza is harvested (and planted) with the same equipment that wheat is. Some irregularity isn't going to matter.

As the seeds are much smaller, this may or may not be the case. The article mentions mills not being able to handle the size, but it could also affect other things.

The seeds are huge compared to, say, quinoa, which is also harvested using a regular old combine. My comment wasn't hypothetical. That is how it is harvested already.

Breeding is increasing the size of the grains.
