ICAO is not EASA; as such, a link to ICAO documents would be especially helpful.

What you are suggesting is a coordinated, simultaneous, global change to the commercial air transport maximum age, across multiple regulatory bodies, happening in the next 3-4 months, when none of the major global players have publicly announced intention of such a change. And that such a change will come in the US via amendment to an existing bill, which again is different than how the change happened in December 2007...more than 10 months after the FAA publicly announced their intent to raise the mandatory retirement age in accordance with ICAO's change.
