As of 2023-07-12, we have resolved all known discussions that might result in normative changes, and all of the normative changes have been presented to TC39 and received consensus. This issue is a checklist and plan for merging those normative PRs into the spec text, so that observers can see the status at a glance.

After completing this checklist, barring fixes for bugs found during implementation, the spec should be in its final normative form, representing exactly what needs to be implemented.

The champions' plan of record after that point is to quickly address two open editorial issues that affect the ISO 8601 grammar, since V8 has let us know that the grammar changes can be disruptive even if they are only editorial ones:

• Use early errors to simplify ISO 8601 grammar #1984 - PR Editorial: Use early errors and parameterization to simplify ISO 8601 grammar #2766
• Collapse grammar nonterminals that are only distinct for the purposes of disambiguation #2006 - PR Editorial: Collapse nonterminals only used for disambiguation #2767

Then, address the lower-priority editorial issues listed in the milestone https://github.com/tc39/proposal-temporal/milestone/11
