Call for testing: OpenSSH 10.0

[BasketCase]

Tested on Gentoo Linux x86.
gcc (Gentoo Hardened 14.2.1_p20241221 p7) 14.2.1 20241221
my configure command and the summary at the end are here: https://bpa.st/2VPA
emerge --info available here: https://bpa.st/LF7Q

make tests returned all tests passed.
It can talk to itself fine.
It can talk to Gentoo's net-misc/openssh-9.9_p2 fine (client and server)
It can login to both of the oldest sshd's I have:
dropbear_2016.74
OpenSSH_7.5
Also, tested running it under tcpserver (ucspi-tcp) and it worked fine.

My only concern is that ssh -v reported:
debug1: Remote protocol version 2.0, remote software version OpenSSH_9.9
I double checked and that was the openssh-SNAP-20250404.tar.gz version
saying that.

Willing to do more specific testing if helpful.
