Various countries have age limits for their own pilots between 60-62 on the low end all the way to no limit on the high end.

So member states can continue to do what they want, as they have already been doing for years, with some states allowing ICAO pilots to operate at a higher age limit within their airspace than their own pilots can.

The path of least resistance for the ICAO bureauracry would be to raise it to 67 to avoid a hot mess for their most significant member. If enough other member states protested vehemently, then it could become contentious.

Think of ICAO not as city hall but rather the board of a condo HOA... and the US is a rental corporation which owns half of the units in the building.
