There is no conflict. You misunderstood what default means. It just
means if you don't explicitly specify GSSAPIAuthentication in ssh_config,
it defaults to "no". But, the openssh package maintainer decided to
specify "GSSAPIAuthentication yes" for some unknown reason.

On a desktop on the same LAN, GSSAPIAuthentication does not introduce
noticeable delay. I have yet to investigate why.
