Is it possible to have an optional config setting to make blockbreaks actually damage tool durability, and not simply "ghost" it?
Might be useful to encourage players to use more than one tool when breaking things like vaults, possibly encourage them to have support structures in place to re-supply and repair when going after larger sized constructions.
If this can be done on a per reinforcement-type basis that would open up tons of new avenues for allowing players to choose which reinforcement to use, instead of defaulting to the one with the most hp.
