I did spend a couple of hours looking at the code, and there are a few
places where the child components do depend on data/methods in the parent
container, even though the "child" objects can be created without the
parent; I'm about 80% sure that there are no guards against calling those
child methods without a parent, so it seems safer to rework my model to
use the top-down approach.
Perhaps I'll find some time soon to learn enough to create some unit tests that
confirm/refute the above, and if true I'll file some bugs.
