Epic #87878: Allow full replacement of filelist module / uninstalling of EXT:filelist
Resolve dependency of FormEngine and FilelistLocalisation
The FormResultCompiler uses the FileListLocalisation module from filelist extension, regardless of whether or not any relevant items are currently rendered:
$pageRenderer->loadRequireJsModule('TYPO3/CMS/Filelist/FileListLocalisation'); in Packages/TYPO3.CMS/typo3/sysext/backend/Classes/Form/FormResultCompiler.php
This should be solved either by integrating the functionality if needed in backend js or as hook - provided in addition - by the filelist module.
