Hi, https://www.openssh.com/specs.html says that RFC8308 support was added in OpenSSH 7.2, and it specifically calls out both ext-info-s and ext-info-c: "Extension Negotiation in the Secure Shell (SSH) Protocol (ext-info-s, ext-info-c)". However, while ext-info-c was indeed added in 7.2 as part of server-sig-algs support (https://anongit.mindrot.org/openssh.git/commit/?id=76c9fbbe35aabc1db977fb78e827644345e9442e), ext-info-s was only added in 9.6 as part of implementing the ext-info-in-auth@xxxxxxxxxxx extension (https://anongit.mindrot.org/openssh.git/commit/?id=a7ed931caeb68947d30af8a795f4108b6efad761). Could this web page be corrected in some way? (This rabbit-hole brought to you by https://bugs.debian.org/1082730 and https://github.com/jtesta/ssh-audit/issues/291.)
