--8<-- RFC 4253 5.1. Old Client, New Server
Server implementations MAY support a configurable compatibility flag

There it was, thanks!
However, it says "1.99" is the same as "2.0" for a client like libssh2 so
doing the proper check doesn't help here.
This said, libssh2 doesn't check the received banner at all for version
numbers or similar.
SSH 1 and SSH 2 protocols are not compatible, and I'm not sure that there
would be any successful packet exchanges *at all* if the server was SSH 1
only.
Oh, I didn't know that. I'm completely unaware of SSH1 details... Thanks for
enlightening me!
