From preliminary Governance model in-file discussions.
In the words of @AnneT

This list is great. We might want to think about how to document these principles best so that both this model and the contributing guidelines in the library reflect the same principles, and have the right amount of specificity depending on the purpose of the docs (e.g. library docs should get way more specific about requirements for some of these)

Acceptance criteria

Library inherent contribution guidelines (CONTRIBUTING.md) are reflecting the commonly reviewed (in designer workshop & developer summit) model steps.
