Thanks for the info. Yea one of my keys is from the previous millennium. But my 
point remains. So you peaked my curiosity. FreeBSD takes no note of this as far 
as I can find. https://www.openssh.com/releasenotes.html covers OpenSSH 
7.7/7.7p1 (2018-04-02)  to openSSH 1.2.3p1 (2000-03-24). And indeed OpenSSH 
5.9/5.9p1 (2011-09-06) notes authorized_keys2 is deprecated. That's not noted in 
UPDATING either. Without the comment in sshd_config it I would still be looking. 
One of the guys I work with has never used authorized_keys2 so I would have 
gotten it eventually from that. Back in the very eary ssh days I wanted to do a 
simple change that was eventually implemented. But from that I know I am not up 
to reading the ssh code.
