excludeDoktypes cannot overwrite some default values

[nm-dh]

In the function getExcludeDoktypes(array $configuration) in the class MenuRepository.php the following doctypes are always suppressed and I have no possibility to activate e.g. the BE User Section via excludeDoktypes.

    protected $excludedDoktypes = [
        PageRepository::DOKTYPE_BE_USER_SECTION,
        PageRepository::DOKTYPE_RECYCLER,
        PageRepository::DOKTYPE_SYSFOLDER,
    ];

protected function getExcludeDoktypes(array $configuration): array
    {
        if (!empty($configuration['excludeDoktypes'])) {
            $excludedDoktypes = array_unique(array_merge($this->excludedDoktypes, GeneralUtility::intExplode(',', (string)$configuration['excludeDoktypes'])));
        } else {
            $excludedDoktypes = $this->excludedDoktypes;
        }
        return $excludedDoktypes;
    }
