Say that this field, on this form, is answered with the last level of the tree it points at.
A row with anything under it becomes a heading in the picker and is refused by every write to this column — the form, a bulk edit, an import and an API caller alike. It changes nothing already recorded, and nothing that names a branch in order to sweep it. Offered only on a field the model declares as one that files a record.
