Deprecation: #97231 - Unused Interface for inline element hook

See forge#97231

Description

The hook $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_tceforms_inline.php']['tceformsInlineHook'] required hook implementations to implement \TYPO3\CMS\Backend\Form\Element\InlineElementHookInterface. Since the mentioned hook has been removed, the interface is not in use anymore and has been marked as deprecated.

Impact

Using the interface has no effect anymore and the extension scanner will report any usage.

Affected Installations

TYPO3 installations using the PHP interface in custom extension code.

Migration

The PHP interface is still available for TYPO3 v12.x, so extensions can provide a version which is compatible with TYPO3 v11 (using the hook) and TYPO3 v12.x (using the new PSR-14 events), at the same time. Remove any usage of the PHP interface and use the new PSR-14 events to avoid any further problems in TYPO3 v13+.
