Is codeSignature required for static framework?

In other frameworks, I've seen codeSignature included in dynamic cases, but this time Apple said, "Signatures are so required in these cases where the listed SDKs are used as binary dependencies." Does that mean that even if the .framework file of the SDK you are deploying is static, you have to include codeSignature?
