Yes, that's what (I think) I'm seeing.

Perhaps. I never went that deep into apt's innards. But, FWIW, I have

  APT::Install-Recommends no;

in /etc/apt/apt.conf.d/95no-recommends -- and apt (apt-get, too) do heed
that advice. Whether they still consider Recommends: while reckoning
dependency resolution I don't know. But yes, it's a possibility.

Well, it's already installed -- and at the end it went well.

The most important lesson for me is that I was barking up the wrong
tree: that was not a real (indirect) dependency, but just a (for me)
non-intuitive decision taken by the dependency resolver.

I guess I've to tell the resolver that I do care about sysvinit-core.
