I believe their goal is 'non-retoolability', since the original suggestion was for scorch mechanics that makes bricks of a building turn black, deweld, and register as 'destroyed', as if it had been burned away. Big Bertha was another part of that suggestion, having boosted scorch mechanics over normal bombs.

Right now, bombs only temporarily destroy buildings, where they can be retooled even after falling apart.
