I am. If as you say below, "everything that could impact changing the key and/or the implications of changing the key should be in scope", then simply calling the workshop as being about "KSK change" that would be a lot clearer.

And, given that, I propose that there be a major topic on changing the signing algorithm to elliptic curve with 256-bit keys. The CFRG will likely settle on recommendations for fast, constant-time curves for signing; these would be excellent targets for a new signing algorithm. The oft-stated benefits would be:

- much smaller DNS response messages for signatures

- much greater predictability for the cryptographic lifetimes for the keys
