A general sequence of events for init

I have this crazy dream. I dream that, for supervision-styled
frameworks, there will be a unified init sequence.

* It will not matter what supervision framework you use. All of them
will start properly after the init sequence completes.

* It will not matter how sophisticated your supervision is. It is
independent of the features that are provided by the framework.

* It will not matter if you only have process supervision, or if you
have something that manages system state fully. They are independent of
the init start-up/shutdown.

* It will be scripted in a minimal fashion. Each stage of the init
would be a "plugin" called by a "master script". The plugins would be
straight-forward, so you could debug it easily.

* It will not matter if you are on Linux or *BSD anymore; the proper
low-level initialization will take place. All that would happen is a
different plugin would be called.

* It would have a system-specific plugin for handling emergencies, so if
the init fails, you drop into a shell, or reboot, or hang, or do
whatever it is your heart desires.

I'm really trying to figure out why this can't exist. What am I missing
(beyond the shutdown portion)? I know there will be the whole BSD
rc-scripts / SysV rc-scripts / OpenRC debate, I'm trying to avoid any of
those. I've used BSD-styled scripts years ago on Slackware, and have
dealth with SysV's crufty stuff recently. I haven't tried OpenRC yet.
