I can't deploy a custom build in my context, and will reuse existing spare
events
like
- 0x050E0000U "Activity"-"unknown wait event"
- 0x0B010000U "???"-"unknown wait event"
- ...

An other idea that may be called a "better wait event error handling"
would have be to display:

"???-xx" unknown event type (xx being the associated number)
in pgstat_get_wait_event_type()

"unknown wait event - yy" unknown event name (yy being the associated
number)
in pgstat_get_wait_event()

giving an extended range of spare events ;o)
