Wrong hint in deprecation log for usage of feInterface
In case some extension is registering TCA changes and setting parameter
$addTofeInterface = 1 in
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addTCAcolumns, the deprecation log will show:
Usage of feInterface is no longer part of the TYPO3 CMS Core. Please check EXT:statictemplates.
This is caused by a wrong assumption that only EXT:statictemplates was setting this parameter.
This wrong hint makes it hard to understand which extension is actually causing this deprecation log entry.
