There are uses for `-A` that aren't just for jumping into hosts. I work on code in ephemeral containers and need to use git against remote git servers. If I had to use a key local to the container, I'd have to constantly add new keys to my git servers. Of course, I have secured by agent from abuse. I use gpg-agent as my ssh agent and make it visually confirm every use of my private key. I even set up those containers to use forwarded GIT_{AUTHOR,COMMITTER}_{NAME,EMAIL} envs. So other people can work on the same container as me and git commits we make are still attributed correctly.
