Nope.

SAC simply manages "port monitors".  The most commonly used port monitor
is ttymon, which is the replacement for getty.

Nothing prevents SAC from being used to control any "Service Access
Facility", be that inetd (aka listen in SysVr4-speak), or individual
TCP/IP port monitors, or anything else that provides a service.

In theory SysVr4 ports should never have come with inetd, but of course
in practice the vendors were swayed by those who wanted a more BSD-like
system, regardless of the fact that the SAC subsystems, including
listen, are generally a more mature design and with a reliable and
simple table-driven parent daemon watching over the flock it's a much
more robust design too.
