No. Arch had been shipping a config file which didn't know about systemd's
socket until about two days ago. Now the arch default has changed. I am not
sure what was the vanilla syslog-ng.conf.

AFAIU when syslog-ng is compiled on a systemd-based machine, it will link to
libsystemd-*.so by default. So, systemd is required unless disabled explicitly
at buildtime. The config file is simply a text file which by itself doesn't
justify a dependency on anything.

In any case, all arch setups now carry full installation of systemd, so this
dependency is not a problem.

However, weren't there some rules which tell to not specify dependecies if
they are in the base group (systemd will be in base, right)? Like for example,
core/which can be replaced by a shell bultin type which is more informative
IMHO. But if you remove which lots of things will silently break.
