Deprecation: #80048 - Mark ExtJS related API calls as deprecated

See forge#80048

Description

The usage of ExtJS has been marked as deprecated. Therefore the following methods of ExtensionManagementUtility have been marked as deprecated:

• addExtJSModule

• registerExtDirectComponent

Impact

Calling any of the PHP methods will trigger a deprecation log entry.

Affected Installations

Any TYPO3 installation working with custom extensions that use any of these methods.

Migration

All of the functionality is obsolete or outdated and should be handled differently from now on:

1. Use ExtensionManagementUtility::addModule instead of addExtJSModule.

2. Some ajax routes instead of ExtDirect.
