It's not enabled yet. I don't think of it in terms of powerfulness, it's more just like a useful feature for collecting ore and obsidian. Yep, it's supposed to take a long time in vanilla, that's why we make mods for that. It's not a problem - just Instant break is faster.
Anything that takes less time to do (IMO) is better. Especially when the result is the same quality! It means you can collect more in the same time frame. (Whatever that is) which means you can build quicker! or whatever it is your collecting for.
I had a chat with Rena last night, and if you want to can my idea in favor of the new one I'm okay with it.
Cheers
I thought it might be a long shot anyway! Thanks Tunes for giving it a go
