It does not strictly _require_ that, but on my system apt would remove
dbus-user-session and quite a few of its reverse dependencies, which is
bad. With aptitude the results are better, as it installs runit-systemd
by default and would not remove any packages.

I think 2) would make most sense, but either of these options looks
preferable to the status quo.
