The spore coat sounds like it could be used as some kind of weapon:

Many harmful chemicals kill bacteria via DNA-damaging mechanisms [10]. However, spores have evolved a number of mechanisms that confer chemical resistance. The spore coat is important in the resistance to many oxidizing chemicals such as chlorine dioxide, hypochlorite, ozone and peroxynitrite [2] [10] [11]. It functions by reacting with these chemical agents and detoxifying them before they pass through the spore coat [10]. In addition, the inner membrane’s extremely low permeability prevents both hydrophobic and hydrophilic molecules from entering into the core [11]. SASPs also protect the DNA by binding to it and shielding it from harmful chemical agents that enter the core

UV radiation damages the DNA of a cell and induces mutations. Saturation of an endospore’s DNA with SASPs protects the DNA from this harmful threat
