In Contao 4.7 tcpdf is not longer Core-Bundle

[netzarbeiter]

Is there a possibility to require the tcpdf-bundle?

I don't think there is any possibility, as long as versions older than Contao 4.7 have to be supported. But Isotope could add

{
    "suggest": {
        "contao/tcpdf-bundle": "For document creation you need to install the contao/tcpdf-bundle when using Contao 4.7 and up."
    }
}

to the composer.json and may be make the core independent from the presence of contao/tcpdf-bundle - and instead give a notification in the back end somewhere, if contao/tcpdf-bundle is missing (in Contao >=4.0,<4.7).
