openssh unix dev - Oct 2025 - openssh.com/pq.html: warning even without explicit kex config?

Hello.

May i dare to ask, i get that warning now that i have updated my
local OpenSSH; i have restarted the local sshd; the server is
AlpineLinux edge, sshd restarted, so both ends run 10.2p1 aka
10.2_p1.  I have no explicit kex configuration, however
HostKeyAlgorithms is ssh-ed25519 (only these pri/pub keys exist).
Why do i get the warning, i thought it is about KexAlgorithms?
The output of "$ ssh -Q kex" is identical.
