Hmm, your subject tricked me, this is not mr-specific. Anyway..

I sometimes just use git:// and in the rare case I need to push from
such a checkout, will git push ssh:// directly and enter a password.

I sometimes set up ssh keys that are only allowed to run git-shell on
the server. This is accomplished as follows in its .authorized-keys:
command="perl -e 'exec qw(git-shell -c), $ENV{SSH_ORIGINAL_COMMAND}'",no-agent-forwarding,no-port-forwarding,no-X11-forwarding ssh-rsa ...

I have this in .ssh/config, so that a special key will be used when
sshing to git.* domains. This way the limited use key is not used when
normally sshing to the server.

Host git.*
        IdentityFile ~/.ssh/id_rsa.git
