Our current workaround looks like:

namespace Codappix\SiteCodappix\Hooks;

use TYPO3\CMS\Core\Core\Environment;
use TYPO3\CMS\Frontend\ContentObject\ContentObjectGetDataHookInterface;
use TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer;

        return Environment::getContext()->__toString();

    public static function register(): void
    {
        $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_content.php']['getData'][self::class] = self::class;
    }
}

Call the register method within ext_localconf.php

Usage in TypoScript:

page = PAGE
page {
    includeJSFooter {
        tracking = EXT:site_codappix/Resources/Public/Assets/Scripts/tracking.js
        tracking.if {
            value.data = applicationContext
            equals = Production
        }
    }
}
