+1. Proposed - A tracking issue has been created with a basic outline of the
+   proposal.
+2. Pending - An RFC document has been written with a detailed design and a PR is

+3. Final Comment Period - A core team member has been assigned to oversee the

+   - An RFC may be reverted or closed during final comment period if a member of
+     the core team or community raises a previously unforeseen issue that is
