That _should_ actually be the default in /etc/ssh_config today. It's a good practice to have

Host *
    Protocol 2

in your ~/.ssh/config just to be on the safe side. Some OSes still come with
Protocol 2,1
in their default config, like OS X.

Emphasis on unused! In my experience PAM is used quite often, again I'm OS X biased here.

I expect these methods to be rarely used.
