Comment (by fhgwright):

 It's not just "Catalina and above".  The ssh-agent provided with some
 older OS versions has some sort of soft compatibility issue with some
 servers, resulting in a warning on every connection.  This was easily
 fixed by using the MacPorts ssh-agent, but that has now stopped working.

 It's probably a bug that the port doesn't supply the appropriate
 LaunchAgent file to cause this agent to be used normally, which is
 inconsistent with the usual behavior where MacPorts-installed tools take
 precedence over their Apple equivalents.  If it did do that, this bug
 probably would have been noticed earlier.

 The required LaunchAgent is easily derived from Apple's:
 {{{
 MacPro:~ fw$ diff /System/Library/LaunchAgents/org.openbsd.ssh-agent.plist
 /Library/LaunchAgents/org.macports.ssh-agent.plist
 6c6
 <       <string>org.openbsd.ssh-agent</string>
 ---
 >       <string>org.macports.ssh-agent</string>
 9c9
 <               <string>/usr/bin/ssh-agent</string>
 ---
 >               <string>/opt/local/bin/ssh-agent</string>
 }}}
 This is on 10.9; I'm not sure how much it varies with the OS version.
