A backend model should always be a \Magento\Framework\Model\AbstractModel

public function addObject(\Magento\Framework\Model\AbstractModel $object, $alias = '')

The methods \Magento\Framework\App\Config\ValueInterface::getFieldsetDataValue() and \Magento\Framework\App\Config\Value::getFieldsetDataValue() are declared but never used

A frontend model should always be a \Magento\Framework\View\Element\AbstractBlock

The method \Magento\Framework\App\Config\ValueInterface::getOldValue() should be removed from the interface because it is used only internally by a particular interface implementation: \Magento\Framework\App\Config\Value

\Magento\Framework\App\Config\Value::afterLoad() method breaks specification of the overriden parent method \Magento\Framework\Model\AbstractModel::afterLoad() by not calling it, ignoring its logic, and having a different result type

How does Magento 2 save a backend config form vield value?

Logical error: Magento 2 checks whether a backend config form field's «backend_model» implements the \Magento\Framework\App\Config\ValueInterface interface only, but actually calls the «backend_model» for much more methods (absent in the interface)

The method \Magento\Framework\App\Config\ValueInterface::isValueChanged() should be removed from the interface because it is used only internally by a particular interface implementation: \Magento\Framework\App\Config\Value
