using the abstract socket is bad for security since you have no
permission checks anymore. And essentially anybody could start owning
that socket. You do not really want that.

Also the system socket address is pretty much hardcoded. At least when I
looked through that a few weeks ago. And then changing the address
becomes quickly big trouble. Only advantage with systemd would be that
you can easily set an environment variable for every process. So it
might work out for you. In general it is a big mess.
