We never expose systemd/bus APIs if there is already an API to retrieve the
given value. That is, our recommendation is to *always* use gethostname() if
you require the effective hostname of your system.

We enforce this policy in quite a lot places, and so far there hasn't been any
reason to change this.

Yeah.. auto-configuration via DHCP makes stuff awfully complicated. What can we
do..
