That link literally says exactly what my comment says. That if you black out on the surface, then, OK, but if you black out in the water then laryngospasm will protect you from inhaling water for a bit (under a minute), but then it will end, at which point you'll inhale water and CPR will become even harder. etc. etc.

Actually, reading a bit about it, laryngospasm does not occur during drowning and so it can't protect you.
The source is "Laryngospasm in breath-hold diving", found in the proceedings of the 2006 Breath-hold diving workshop:
https://www.diversalertnetwork.org/files/UHMS_DAN_2006_Breat...
Vocal cord closure is certainly protective in the initial stages of an immersion accident. This occurs only when the victim is conscious. A person who is unconscious when they enter the water or who loses consciousness in the water will not have protective laryngeal reflexes. If consciousness is lost during static apnea or in an underwater swimming contest, the vocal cords will relax and will not close in response to inhaled water. Similarly a breath-hold diver who loses con sciousness will not develop laryngospasm.

Sure, but if you have a buddy, a minute is more than enough for a rescue. I did it a couple of times from about 10m and it is a bit stressful but I got free beers in the end :)

Sounds like fun. Maybe drown-and-get-rescued should be introduced as a new sport.
