At least on Ubuntu 19.04 the socket is now placed in /run, making it accessible:
zyga@fyke:~$ echo $SSH_AUTH_SOCK /run/user/1000/keyring/ssh
Having said that, there is no interface exposing access to the agent. I'm marking this as confirmed / whishlist, as this is a new feature. Please escalate to have it investigated faster.
