As far as I understand owned object were supposed to be the widgets
contained inside the containers. Not all widgets are contained (toplevel
windows are not), also not all objects are widgets.

I can't tell for sure. Maybe (as I wrote before) the floating reference
feature was not always expected to exist, maybe it simplified some
things, maybe it does not matter that much and the system works the same
no matter if the initial reference count is 0 or 1 or some other number.
