The breeze can be damaged by wind charges and will eventually die if attacked often enough.

This seems not to be intended, given that breezes have been made immune from all other projectiles and wind charges seem to behave mostly like projectiles (e.g. they work in connection with the target block)

Repro:

Create creative world with Experimental Data Pack enabled, spawn a breeze via spawn egg, get yourself a few wind charges, shoot wind charges at the breeze and observe

1) the breeze taking a red damage tick, as well as

2) it eventually dying.
