Heh, but the s6-svc interface change in version now breaks it.
However, a simple patch to OpenRC's code changing the 's6-svc -Dd'
invocations to 's6-svc -dwd' can fix it, until upstream notices and
makes the necessary changes.

But leaving that small detail aside:

I'm not sure if this is a question or not, but unless I am not
understanding you correctly, then yes, that last part is more or less
what OpenRC's "integration with s6" feature does. It's not just
launching s6-svscan, you can use OpenRC's dependency and ordering
constraint specification support with services supervised by s6, just
like with any other service. Provided you did write the init script as
specified by OpenRC's documentation.

If you don't look too closely, you could also say nosh without the
userspace terminal and login services stuff more or less covers the
same ground as s6, s6-rc and a small subset of execline.

If someone does want to look closely, this page is now a lot more
complete than last time I checked (or as I remembered it being):
