Have you tried his suggested workflow? I think it's a useful workflow, and if I hadn't found a workflow like this already would appreciate the pointer.

I guess he could write a code harness to do this, or gin one up really quickly, but that kind of tooling today seems like the purview of the practitioner -- you -- it's frankly faster for you to spec what you want to try this idea out if you want it automated than it would likely be to deal with his code.
