I just stumbled over

  http://refspecs.linuxbase.org/LSB_4.1.0/LSB-Core-generic/LSB-Core-generic/initsrcinstrm.html

which specifies pretty much what we talked about above:

  /usr/lib/lsb/install_initd /etc/init.d/example.com-coffeed
  /usr/lib/lsb/remove_initd /etc/init.d/example.com-coffeed

So we could make systemctl just call this if it's available, and
otherwise do nothing for init.d scripts.

I'll cook a patch for this.
