Careful. Objectively that's not exactly what the WP says.

It could be interpreted to be "raise the age now" and study it as we go to make sure it stays safe.

I suspect it was deliberately crafted to be vague, looks like the emphasis is on supporting member states who may be reluctant to make their own decision. But if certain entities are pushing this, it doesn't matter what other member states do, as long as THEY can raise their own age (or already have), and the ICAO age goes up, they can still get whatever benefit they're looking for. They don't really care whether Lichtenstein and Namibia raise their age or not.

I speak fluent bureaucrat, from years in mil HHQs. At that level nothing is accidental. Kind of like Retroactivity vs. Non-Retroactivity.

Also this is interesting:

2.2.6
The two leading concerns for future risk of medical-cause fatal accidents are mental health conditions and problematic substance use (e.g., alcohol and other drugs). These potential causes of aviation related fatalities tend to present in a younger demographic.
