This message starts a two week consensus call on whether draft-ietf-tls-rfc8446bis should prohibit key share reuse between connections. ekr has already produced a PR; see [1]. Please let the list know whether you do or do not support this change by 6 April 2026. Please note that if you already replied in here:[2] there is no need to also reply to this thread unless you changed your mind.

Note that as draft-ietf-tls-rfc8446bis in currently in AUTH48, this may add some delay to its publication. We believe that any delay would be small because we already know there are outstanding PRs that needed to be worked.
