In piuparts tests with fake-essential init-system-helpers I currently see 
these leftover directories in several tests:

2m30.1s ERROR: FAIL: Package purging left files on system:
  /etc/systemd/	 not owned
  /etc/systemd/system/	 not owned
  /var/lib/systemd/deb-systemd-helper-masked/	 not owned

if i-s-h uses /etc/systemd/system to place something in there and other 
packages may do the same, the only sensible solution is that they all own 
that directory (aka ship it) and noone does mkdir/rmdir manually.

You don't have to worry about the reference counting, dpkg does take care of 
it. Just ship the empty directories (lintian does not complain about empty 
directories in /etc). Once the package gets removed and it is the last owner 
of a directory it will be removed by dpkg (if empty).
