Sure, but it's inconvenient to wrap git-fetch and git-pull in ssh-agent/ssh-add/kill if you want to get exactly one password prompt per logical remote-using operation. Personally, I like that when I do operations involving authorized access to a remote machine, I need to enter my password. But once per command is all I want.
