Yes, for the purpose of compatibility, it's the only choice, as I can see.

To sum up, I'd like to implement:

1. <path> is configured by --socket, then put it here.
2. else if `~/.git-credential-cache` exists, put the socket under here.
3. else, put the socket under
`$XDG_RUNTIME_DIR/git/credential-cache.sock`,
if $XDG_RUNTIME_DIR does not exist, default to
`/tmp/git-$UID/credential-cache.sock`.

As a result, new user will use xdg-compatible path while old user will not
be surprised.
