TYPO3 Core

I am adding a category field like this:

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::makeCategorizable(
    $_EXTKEY,
    'pages',
    'tx_wakapublicsolr_publication_facet_categories',
    array(
        'label' => 'LLL:EXT:wakapublic_solr/Resources/Private/Language/locallang_db.xlf:pages.tx_wakapublicsolr_publication_facet_categories',
        'exclude' => FALSE,
        'displayCond' => 'FIELD:doktype:=:1',
        'fieldConfiguration' => array(
            ...
        ),
        'l10n_mode' => 'exclude',
        'l10n_display' => 'hideDiff',
        'position' => 'after:tx_wakapublicsolr_publication_download'
    )
);

The goal is to show this specific category field only on normal pages (doktype=1).

Internally, \TYPO3\CMS\Core\Category\CategoryRegistry::addTcaColumn($tableName, $fieldName, array $options) is called, which contains this assignment:

            $columns = array(
                $fieldName => array(
                    'exclude' => $exclude,
                    'label' => $label,
                    'config' =>  static::getTcaFieldConfiguration($tableName, $fieldName, $fieldConfiguration),
                ),
            );

Here, $options['displayCond'] is dropped!

Therefore, all category fields can only be shown on all records, disregarding display conditions.
