Customizing ssh parameters in git

Question

From the docs on GIT_SSH environmental variable:

GIT_SSH, if specified, is a program that is invoked instead of ssh when Git tries to connect to an SSH host. It is invoked like $GIT_SSH [username@]host [-p ] . Note that this isn’t the easiest way to customize how ssh is invoked; it won’t support extra command-line parameters, so you’d have to write a wrapper script and set GIT_SSH to point to it. It’s probably easier just to use the ~/.ssh/config file for that.

However, when I try to do something like

GIT_SSH="ssh -i /path/to/key" git clone <repo_url>

it works just fine. Why does the documentation say that no extra command-line parameters are supported?

That documentation is not up-to-date, and does not mention the actual environment variable that introduced extra command-line parameters: GIT_SSH_COMMAND (Git 2.10+, Q3 2016.

It is also configurable with the setting core.sshCommand.

Since Git 2.10, GIT_SSH and GIT_SSH_COMMAND has been made equivalent.
The setting ssh.variant replaces what GIT_SSH did before.
