There's some chatter that suggests Unix domain sockets were

 I haven't checked myself; even if the basic Unix domain sockets
mechanism was added for IPC, it's not clear if the access rights
transfer functionality was also implemented.

Last I heard the domain sockets were just an emulation, implemented in
terms of loopback AF_INET sockets.  The most annoying limitation of the
implementation that I remember was that you had to define logical names
in the system table to tell it what ports to use:
$ define/system TCPIP$AF_UNIX_MIN_PORT 1000
$ define/system TCPIP$AF_UNIX_MAX_PORT 5000
SCM_RIGHTS _is_ defined in socket.h, but that may not mean much.
