Thanks, Martin. This is correct. So there are two ways to fix this: As Martin suggests, make TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA one of the MTI instead of the current, or Add 0xC0,0x23 (TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256) to the list of ciphersuites.
The first seems more consistent to me. Chairs: guidance? Note that the document is in the RFC editor queue so we’ll need AD approval for the change at this late date.
