The use case is that the entire globe is both incompletely mapped and also constantly changing: having it all editable is much easier than differentiating each and every case where some element might or might not change frequently. Such a system of differentiation of map elements by likelihood of change could be good in the long term, but it would be a huge undertaking to classify them.
