Requesting an option to disable ravager block damage. To go alongside all the other options that disable direct grief / block damage.

Can confirm this, adding the flag solves it

is this a joke

No?

They can also destroy certain block types by charging into them.

These settings exist, so I don't see it being outside the scope of WorldGuard.

block-tnt-block-damage: true
block-creeper-block-damage: true
block-wither-block-damage: true
block-wither-skull-block-damage: true
block-enderdragon-block-damage: true
block-fireball-block-damage: true

I had someone complain of a ravager being used to grief to break through custom trees and a hedge entrance / fence.

ah, thought you were asking for a flag. which already exists. and can be applied to the global region. i guess it could also be added as a config option, but it doesn't seem pressing atm.
