I think such discussions would benefit from the basic premise that "secure" is a relative notion. It is completely pointless to ask if a protocol is secure or not secure, unless you first present an exhaustive list of security claims. That is, you can't ask if TLS 1.3 is secure or not, without first describing what security is to be expected from different scenarios. In a sense, *every* protocol has the potential of becoming broken, unless it is unambiguously defined what is proper and improper usage of the protocol.
