This is exactly what is happening. I'm still involved with talking
about this with the OpenRC upstream folks on their IRC channel, and
while I've not yet had a chance to begin packaging it, there's a
repo on collab-maint in preparation for that. In order to make
OpenRC usable in Debian, we need it to be able to work with LSB
scripts, but it's not yet clear on how to do that. An upstream
developer was initially keen to look into doing this, but it looks
like they are now short on time, so we might need to do that part
ourselves in collaboration with them.
I'm short on time myself, so if anyone wanted to join in with
doing this, I'm sure we could set up a proper mailing list and
start moving things a bit faster.

This is already in the works. It can be removed right now. The only
thing stopping it is just investigating the impact on removing the
Essential flag on the installer etc. If there are no deleterious
consequences of this change, it can be made in the next upload. Any
advice on doing this would be appreciated, e.g. in case this would
make it more liable to cause breakage if apt could remove sysvinit
and result in a broken system.

AFAIK this is exactly what's happening. While I've been working on
sysvinit I've made numerous changes to better accommodate systemd and
upstart, and with the latest experimental uploads it includes some
changes to better work with upstart. There's no blocking involved--
I've been happy to make changes that improve things for alternative
init systems, and make migration easier, while also making things
better for everyone. So long as it doesn't have a negative impact
on existing sysvinit users, no changes have so far been refused.
While I have personal reservations about making systemd or upstart
the default at this time or in the near future, I am nevertheless
keen to make their support in Debian top-notch, and I will continue
to work on reorganising sysvinit to make this even better.
WRT supporting multiple init systems, I certainly don't think it's a
wise move for packages to support multiple init systems. If we
change the default, we should e.g. provide a means for sysvinit to
run systemd service units to allow for a smooth migration, and
amend policy so that all packages provide files in the same format--
we don't really want to have fragmented support for different
systems within Debian, though supporting different init systems as
the present is needed and desirable.
