Thanks @jared. I agree that the post you linked is a great starting point and might just need some minor updates since it was published in 2020. The next step could be a more living checklist for each proposal to verify that each step was performed to be verified by community participants. Preferably, I think this should be done through codebase PRs to keep everything in one place.
Compound III codebase tooling is definitely superior to V2 so this is another reason to push for a migration to the new markets.
