but "because in case of systemd, forking to background is useless" is
simply as *WRONG* as something can be

'foreground' implies Type=simple and if you have ordered services after
clamd they are immediately started while clamd is *not* ready to accept
connections because it's loading the signatures which can take a long time

it breaks a startup chain like "clamd -> clamav-milter -> postfix"
ordered with Before/After and i even wrote a distribution-bugreport to
switch from foreground to forking because clamav-milter reported errors
at boot

If set to simple (the default if neither Type= nor BusName=, but
ExecStart= are specified), it is expected that the process configured
with ExecStart= is the main process of the service. In this mode, if the
process offers functionality to other processes on the system, its
communication channels should be installed before the daemon is started
up (e.g. sockets set up by systemd, via socket activation), as systemd
will immediately proceed starting follow-up units.
