Let's take the inverse view: which of these use the upstream sysvinit 
scripts directly ? The answer, as demonstrated below, is: none.

(I've only looked at current sid versions and checked in the debian/ 
directory. Feel free to run your own investigations using the fantastic 
sources.debian.net.)

The above IMHO demonstrates quite clearly one of the advantages of 
systemd over sysvinit: for all of the examples you took, Debian is 
currently using a Debian-specific sysvinit script (I haven't 
investigated the reasons though), all of which are quite redundant. They 
are not shared across distributions at all.

So, the upstream examples you chose actually demonstrate that these were 
not targeting Debian enough for the Debian maintainers to use the 
provided init scripts (if these were even provided). (Note, I'm not 
claiming Debian will not need to modify the eventual systemd 
configuration files either, even if I think it's less probable.)
