Most programs will keep application-related data relevant to all
instances running which is not configuration data suitable for dconf nor
something for which you want to set up a formal database to deal with
change notification and resolution.

Apart from that, quite frankly it is I think what most users expect
for programs having only one main window. The principal problem at the
moment is gtk_window_present(): a user starts a program (she may have
forgotten it is already running if it is minimised or on a different
desktop) and gets presented with ... some odd blinking thing in the
panel if she is attentive enough to spot it at all.
