Breaking: #96829 - Removed BackendUtility->getFuncInput()¶
BackendUtility::getFuncInput() is incompatible with
handler, and has been removed.
Instances with extensions using the method will raise a fatal PHP error upon use.
The method is part of very old-school backend module code and of limited use. TYPO3 Core code does not use it since at least v9, it is relatively unlikely backend modules of extensions still use this method. The extension scanner finds usages with a strong match.
