Because dbus is slow and unreliable.
a.) restart dbus daemon (and keep everything communicating to dbus
    still working) is not supported by upstream in a sensible way.
    [1][2][3][4]
b.) dbus can not be used over network
    You have to setup a proxy for dbus to use it over network.

We have other speedy and reliable IPC to be used for single instance
apps. Why I have to use dbus just because I use GTK+ at the same time?

This topic is started by Murray Cumming because he is trying to wrap
GtkApplication for gtkmm. Why we force all gtkmm users to use dbus?

As I have said, I have nothing against GtkApplication, I just do not
want to us dbus.

How can you improve dbus when it is designed to not support restart and
over network?

Crash is not always due to internal bug or unstable software.
a.) inadequate resources
    For example, you open a really large file in an editor.
    The editor freeze and you want to kill it, but the editor
    still has other windows opened.
b.) dbus restart / dbus crashes
    Congratulation! Your well-written, bug-free single instance app
    crashes.
c.) killed by user

I like single instance. I have said it is good in my first reply.
I just do not want everything to be single instance.

Kind regards
