> @mgkwill thank you for doing this. I need to check out the PR locally and give it a test drive, but eyeballing it looks like you are on track. It unfortunately means there is some duplication in generation logic, but that seems unavoidable. Moving to this area is a prerequisit for integration into the mainline.

Happy to do it. I stumbled upon the issue when I needed to run some of the tests. It seemed like something helpful and I thought it would be nice to get benchmarks into mainline. Let me know how the local test works.

Sounds reasonable to me. More guidance here and I'm happy to help there also.
