Init.d scripts are just shell scripts.  All somebody needs to do is
write a shell script that parses a unit file and does what it says,
and exports an openrc-oriented init.d environment.  That can be
packaged separately, or whatever, and maybe an eclass could make it
easy to install (point it at the upstream/filesdir unit and tell it
what to call the init.d script, and you get the appropriate
symlink/script).

The OpenRC devs don't have to endorse anything - sure it would make
sense to bundle it, but it could just as easily be pulled in as a dep
or used manually by a user.

The script could ignore any unit features that aren't implemented.
You can ignore settings like auto-restart/inetd and just use the
settings that get the daemon started.
