Devuan us a separate Debian with its own repositories (and presumably many packages patched to improve systemd-less life), while this is just replacing Systemd with OpenRC on a Debian system, while keeping Debian repos etc.
You're going to have to make a separate repo for everything anyways, because you'll have to change all the init scripts and whatnot that get supplied with programs... well, unless you install both and just leave the useless systemd files laying around forever.
