Nobody to reply to you, so i do it in first:

Air vent are useful on any kind of board.
In first, i put air vent on my custom board to allow breathing the EPS during fixing dings. Otherwise , air bubble blows the resin when it is going off.
During heatwave, for bamboo or other kind of reinforced layers i think air vent can't do no much against delamination if some pressure water stream want to burst between the layers of deck reinforcement.
