I'm very tempted to say systemd in Debian should just make these 5
symlinks to preserve traditional Debian behaviour, at least for
jessie. It doesn't really even need to run systemctl, it can just use
ln -s or whatever. People who are so desperately short of memory that
5 agetty instances are undesired can always disable them.
If you want it to be clear that it's a Debian-specific thing that's
pulling them in, maybe it would be better to add a new
debian-gettys.target or debian-gettys.service that Wants them, and make
it WantedBy an appropriate target?
We can reconsider in a few months for jessie+1, at which point these
will hopefully be clearer:
* how many people switch to systemd and how many stick to sysvinit
* whether kdbus is likely to be merged by the time the kernel
for jessie+1 freezes, making dbus-daemon entirely
unnecessary on systemd systems
* whether we can get rid of init from Essential so chroots don't need a
/sbin/init (yes I know chroots don't necessarily have

I'm not delighted by the idea of dbus-daemon escalating from standard
to important. I install it on my own headless machines, but I know a
lot of sysadmins are more change-averse than me.
Also, installations with sysvinit (or no init at all) really shouldn't
need it, and we don't have a way to make it "conditionally important"
depending on init system (other than the Recommends that systemd

My instinct is that that just sounds like an unnecessarily complicated
way to add 5 symlinks or a Wants that could equally well be there
A generator could be conditional on the absence of dbus.service, or
some such, but then again so could a debian-gettys.service with
