The new launch process workflow wouldn't let me do an Intent to Ship for this one, at least not without some as-yet-unknown gate based on this email. I've filed an issue to get it resolved.
It would be great if the API owners could treat this as an intent to ship, but I'm also fine resending it with a different title.
