The Ubuntu package name is "jackd2", but actually _not_ _jackd_ does
use _dbus_, it's _jackdbus_.
"Desktop" apps could use dbus, a https://www.freedesktop.org/ thingy. As
everything else related to https://www.freedesktop.org/ dbus could be
useful, but not necessarily is useful for every task. A bowling ball is

I don't know why the Ubuntu Studio team makes it the default for Ubuntu
Studio. There seems to be no way to successfully argue against it. DAW
users very seldom need jackdbus and other users very seldom need the
jack sound server at all.
That jackdbus is installed seems not to be related to issues. Nothing
ever auto-starts jackdbus on my Linux installs. I'm running Arch Linux
as well as an "expert" Ubuntu install:
[root at archlinux moonstudio]# systemd-nspawn -q
[root at moonstudio ~]# grep PRETTY /etc/os-release
PRETTY_NAME="Ubuntu 16.04.2 LTS"
[root at moonstudio ~]# dpkg -l jackd2 | grep ii
ii jackd2 1.9.10+20150825git1ed50c92~dfsg-1ubuntu1 amd64 JACK Audio Connection Kit (server and example clients)
[root at moonstudio ~]# cat /usr/share/dbus-1/services/org.jackaudio.service
[root at moonstudio ~]# logout
[root at archlinux moonstudio]# grep PRETTY /etc/os-release
[root at archlinux moonstudio]# pacman -Q jack2
[root at archlinux moonstudio]# cat /usr/share/dbus-1/services/org.jackaudio.service
On both installs jackdbus is inactive.
