User blog comment:RaptorRex606/Block Breaking: Both the Greatest and the Worst Feature/@comment-31746702-20180921190758

The problem with block breaking in my experience is that it straightjackets you into making perfectly flat exhibits, with no trees or foliage, with iron or reinforced glass walls, that's it. Want to do a hilly exhibit with trees and a river? Nope. Smashy-smashy time.

That being said, I do like the feature as an idea. The thing is that there needs to be some perhaps unintuitive exceptions, those being dirt, wood, tree leaves, normal stone and sand (as well as a few more for Biomes o plenty users). That way, you won't have a dinosaur destroying a hillside or destroyingall the trees. Sure, the player could cheat and make exhibit walls out of dirt and stone, but that'd be an honesty thing I guess - if you're gunna do that you probably won't have block breaking on anyway. As it is, anyone that wants pretty exhibits has it disabled, in fact I don't think I've seen a single youtuber with block breaking on.
