Can confirm this as of 8/25/2023, update 1.20.15. Creeper and TNT explosions in water don’t deal damage. I tested it with water and without; when I remove the water everything around the charged creeper dies when said creeper explodes. When the creeper and mobs are in water, however, no damage is dealt when creeper explodes.
i’ll work on testing with mobs in water but creeper out of water.
Edit: if the creeper steps out of water and explodes, mobs standing in water are damaged.
