+Feature: #81330 - Trait to migrate public access to protected by deprecation
+============================================================================
+
+See :issue:`81330`
+See Important-81330-DealingWithPropertiesThatAreMigratedToProtected.rst
+
+Description
+===========
+
+A new PHP trait (:php:`PublicPropertyDeprecationTrait`) is added to support the smooth migration of public properties to
+a protected or private state of a property. By using this trait, deprecation warnings are thrown until the next
+major TYPO3 version.
+
+Impact
+======
+
+Instead of creating a breaking change by setting a public property to protected, the migration can now by done by the
+softer path of deprecation. This will encourage the encapsulation of core classes that still have public properties.
+By reaching encapsulation, refactoring becomes a lot more easy. The core can be modernized more quickly with less
+issues for developers.
