well, you do... i dont (this system was bought preinstalled with 12.04
and upgraded since):

ogra at styx:~$ grep PRETTY /etc/os-release 
PRETTY_NAME="Ubuntu 16.04.1 LTS"
ogra at styx:~$ sudo systemctl status lightdm|grep init.d
ogra at styx:~$ sudo systemctl status lightdm|grep systemd
   Loaded: loaded (/lib/systemd/system/lightdm.service; enabled; vendor
preset: enabled)
  Drop-In: /lib/systemd/system/display-manager.service.d
ogra at styx:~$ 

no idea how you got there ... /etc/init.d/lightdm is definitely not
used in any of my 16.04 installs here (and isnt supposed to be) ...

well SuSE nowadays uses systemd too ... 
perhaps you could convince him then to provide proper systemd
integration ;)

so arch uses the exact same setup just in a different path and via a
hack at build time, but you call ubuntu a hybrid ?

well, if they like to carry a patch against debian ... usually the
proper way is to try to send your fix to debian to not put more burden
on the *buntu maintainers but have it properly coming down the drain in
the future (and not having to spend time to manually merge packages
every start of a release cycle)....
