You can switch to a different protocol or location for the push command. Advantage is that you can clone a repository using git://git.xfce.org/... which is faster than a ssh connection (no login, permission check and encryption), but push to ssh.

git config --global url."ssh://git@git.xfce.org".pushInsteadOf "git://git.xfce.org"

git config --global url."ssh://git.xfce.org/".insteadOf xfce:

After this, you'll be able to do, for example:

git clone xfce:xfce/xfdesktop
