nit: it will [update] -> the widget should typically [update] it's controller's [value] to reflect the focus change visually?

You're right that the widget isn't required to update its MaterialStatesController to match its intrinsic state. There are no examples of widgets that don't do this and I don't know of a use case where it would be useful to do so, so I think it's OK to leave this strong statement in place.
