By design, syslog funnels all logs through a single socket. Separating
them again requires matching the contents of log messages, which is
inefficient and error-prone. Getting syslog to work in chroots can be
annoying, since it requires opening the logging socket before chrooting
(which requires support by the daemon), or providing a /dev/log socket
inside the chroot.

That said, I'm aware that syslog is more convenient in some setups, so
offering both stderr and syslog logging sounds reasonable to me.

Cheers,
