Shepherd by itself doesn’t make any decision; it’s up to the service to
choose whether to log to stdout/stderr or to syslog.

As I wrote in the cover letter at <https://issues.guix.gnu.org/71118>,
Shepherd 0.10 already does a good job at handling logs, which makes
gives less of an incentive to use syslogd; on top of that, 1.0 (current
‘devel’ branch) can display messages logged to stderr/stdout directly at
the command line:

It’s a slight quality-of-life improvement.
