At a glance, this appears to only list the packages which directly
depend on libsystemd0 or systemd.

I'm thinking of multi-step dependency chains. The one which I mentioned
having noticed, reported, and gotten the maintainer to find a way to
drop, was four packages long:

[the original package] -> gvfs -> gvfs-daemons -> udisks2 -> libpam-systemd

The final step of which which is not systemd itself, but does introduce
behavior changes which I find undesirable, even with systemd not
present.

I don't know of any single command - or even self-contained set of
readily reusable commands - which would have identified the fact that
installing the original package would have pulled in libpam-systemd,
except for trying to install it. Even once that's been determined, I
don't know of any way to determine what part of the dependency chain
results in that happening, except to 'apt-get install [packagename]
libpam-systemd-' (and repeat, adding more "no, don't install this
package either" blockings of alternative dependency resolutions, until
the resolver fails to find a solution).
