The more effective rapid fire fighting becomes, perversely there is more demand to tolerate more fuel near structures because there is less expectation of losses. If that demand is met, when the rapid response fails, the fire will be more catastrophic. It's like, having a gun for personal security can be more dangerous than going unarmed if the gun gives you unreasonable confidence.
