Addresses an annoying issue.
Also easy to read code, therefore highly extensible for those that care to make custom ore deposits.
I see surface level ore farms becoming a thing. May or may not be intended, but if that stuff gets regulated it should be toggleable.
Also someone who might have made building floors and roofs from default:stone migh have a surprise. A very niche case though.
This mod is a gamechanger for people doing multiplayer and server admins.
