What's sad is this is the kind of thing that makes Debian unstable in my eyes. Being able to choose whatever init system you want on your Linux distro is something that should just be a thing.
Additionally I'm confused are these packages not pulled from another source or is Debian the sole developer of this one? I would expect support for other init systems to be in parity with the parent project of the package in question as a result of basing your work off of theirs.
My only experience with Debian packaging is at work and not involved with actual Debian maintainers so I'm unsure of their own process. Is there someone who can shed some light on this?
