the ability for any blocks generated in any modded or none modded structures to be unbreakable.. idk feel it'd fit this mod BUT idk how complicated that may be to add but could be a useful feature if you don't want certain spawned in structures to be breakable but still want the block they are made with breakable in game

Minecraft only knows the general position of a structure, not every block generated within it, and even finding that general position is usually not instant, so it would likely cause consistent lag when breaking blocks. Unfortunately this is near impossible to accomplish.
