I can't really imagine GSettings knowing about MY use case and HOW I
manage my settings.

That GSettings wants to offer mechanism to enforce a schemas, fine.
That GSettings crash because a schema is missing, not so much. After all
Gtk not crash when you pass NULL to a gtk_widget_*() function, it does
not crash if the GtkBuilder file ain't found.
That GSettings does not allow me to use it in a RELAXED way, not fine.

Or not. My code is *designed* to actually manage default value. Like UI
has default that people whine about. This is just good programing practice.

But the consensus seems to be clear for me. Glad that I abstracted
preference management already thinking at the time that gconf would go away.

The only reason I jumped into the thread is because I encountered the
problem. I even filed a bug thinking that eventually things would settle
and actually get fixed. But reading all for this it end up being
horribly disappointing.
