It is not necessary, but developers are using it :)

I don't use it either, but that's not the point. If an application has
support for a feature, and that feature is cut around libWhatever, you
need to link libWhatever in. And if libWhatever needs to contact
serviceWhatever, it must be working properly before the app start,
because an application cannot know in advance whether you will print a
document or not...

I need to keep libdbus installed only because surf uses libwxgtk,
which in turns depends on libgtk2, which in turn uses something else
that is linked against libdbus. Go figure...

/etc/machine-id has literally *nothing* to do with dbus. It comes from
systemd, and is not present in any genuine Devuan install. You can
remove it and apparently no application will be affected in Devuan.

That's only part of the story. There are also a lot of D1rs who just
use Devuan as their standard desktop. They are not interested in
tinkering, and they just want to use their computer with a reasonable
distribution. There are Devuan installations which run as public
kiosks, and more that power high school and university labs. In all
these cases, Devuan must *just work*.

If Devuan was just "big servers", we would have dropped most of what
most of us consider "nonsense" since from the beginning. But Devuan
aims at providing a universal, dependable, stable, free operating
system. There are many more use-cases out there than anyone of us
alone can imagine, and we need to support as many of them as possible,
if we want Devuan to survive and thrive ;)

And derivatives are welcome to do that, if they like.
