We probably mean the same. GtkTable for example simply
g_list_prepend()s in gtk_table_attach() -- thus I would just not use
the word "position" here.

That said, does it sound entirely off to gtk veterans trying to
implement widget position as a read-only container child property?

Sticking to the table example above -- a table child's position could
easily be calculated using row (-count) and column (-count). From a
quick look over the code this might not be quite as easy for box
widgets, but maybe the child position could be calculated in the
allocate() run and cached inside GtkBoxChild.
