Description
Using TCP sockets on localhost raises concerns about local privilege escalation attacks. AF_UNIX sockets are more efficient and more secure.
Advertising AF_UNIX sockets over DNS-SD makes little sense, and accepting such an advertisement has its own security concerns. Specifying the AF_UNIX socket in a configuration file is more logical, IMO.
