Some unreliable predictions for 2015

Debian or Debian based distribution and or distribution in general that ship and thus "support" more than one init system will ship two components or two sub component depended on said init system.

In Fedora FESCo/FPC in it's infinite wisdom allowed for sysv initscripts being shipped in a separated sub component after unit migration even thou it made no sense and had no practical purpose.

If I can recall correctly maintainers of about 30 components decided to take advantage of that thus supporting both systemd units and the legacy sysv or upstart ( no distro migrated to native upstart configuration file otherwise everybody would have been done arguing since it would have been the same amount of transition pain ) but none of the maintainers of components that make up the core/baseOS and depend on an init system did , hence even if you wanted to use those components on a systemd free system you could not since you could not boot one ;)

I assume other distro went through same/similar "migration" process but in the case of Debian or Debian based distros or simply distro that are supporting more than one init system, the maintainership burden will be multiplied by the number of supported init system as well as bug reports and the user frustration that goes hand in hand with that when things dont work as expected ( things work fine on init system x but not y, the component only ships init system configuration file for init system x not y etc ).

And I dont think the fight for Debian with the freedom to choose the init system will be ongoing but rather the community will simple refer those that want that to that self proclaimed VUA crowd and the fork they based on Debian.
