Yes, I know that changed. It was an example of something that works with TLS 1.2 even when PFS is used. With TLS 1.3 server or client implementations can find other ways to retain long-term records of session keys. The capability to do that is not a requisite or desirable protocol feature. Different user communities will have different needs, and the best solution is to provide security by default, and cede control of the result to the endpoints. -- Viktor.
