Many thanks for the update Anand.
Could you give a bit more detail on why you decided to dump the ZSKs? Was it just a matter of having fewer keys to manage and fewer moving parts that could break?
Managing keys isn't an issue, since it is all automated by the signer. Our main reason is that we do not have separate storage for the KSKs and ZSKs. They were all stored together on the signer. Additionally, our ECDSA KSKs and ZSKs were of the same size. Therefore, there is no additional protection offered by separating them, and so it is reasonable to use a CSK.
