Wind Charged makes mobs execute an small air burst explosion after death.
When we set the carpet rule "optimizedTNT" to true, the on death effect changes to a normal explosion, including the damage (just like a TNT explosion, even destroying blocks)

• How to replicate it
  Go on creative mode;
  Spawn any mob *(only tested with stray) with an egg, and give the potion effect to it (using splash potion or lingering);
  Kill it;

This makes the new Ominous Trials unviable.

yep i can confirm this happens breeze charges explode like tnt when optimizedTNT is true

It happens with all the wind-charged related effects. I was playing some survival and we kept getting blown up by mobs like Bogged and Strays when they had this effect applied. As soon as a player interacts with a wind charge, it turns into an explosive. So if a Breeze throws a wind charge at you, it works as expected, but when you interact with it by hitting it, it turns very explosive. When killing anything with a maze (from ~2 blocks+) there's also a gigantic explosion and it instantly kills the wielder too.
All our Trial Chambers look like a warzone now.
Turning the rule off fixes it.

I recorded a video preparing to report this bug, then realized it was already reported. Ill link the video here just in case, I showcased different enchantments with optimizedTNT on and off
