Is it necessary to extend MagentoFrameworkModelAbstractModel for all custom model classes in Magento 2?

I am working on a custom model that does not involve any database interactions (e.g., saving, loading, or deleting records), and I noticed that AbstractModel depends on deprecated components like MagentoFrameworkRegistry. Is it mandatory to extend MagentoFrameworkModelAbstractModel for all custom model classes?
