I'm not sure what needs to happen next with this, procedurally. Does it need to be presented to TC39 for consensus? (FWIW, this is why I preferred that we point to CLDR and not duplicate this info in the spec text) |

I'll note: CLDR doesn't have nearly as much detail as we want (like the arithmetic year stuff), referencing it wouldn't be great i think. |

Let's agree in TG2 this week that we want this, then we include it in the Stage 3 presentation. |

The latest version of unicode-org/cldr#4519 seeks to align with Temporal Intl Era Month Code, but it also removes more of the old era aliases.
I think we should land this PR along with the CLDR one, because we can add the aliases back, but it is hard to remove them. We don't have any evidence that these era aliases are in use.
Ideally we would have removed these before Stage 2.7.
I guess this is Normative, but it is also trying to align with CLDR, but CLDR is trying to align with Intl Era Month Code.
