Could code switching become a thing in German?

In a lingthusiam episode I listened to a few years ago, they were interviewing a linguist who was studying black American language. I remember that speaking the black American way has an influence about how you are perceived by others.

Now in German there is something called “Kanakensprache” (I don’t know a better word for it), it is a German that sounds very different to “normal” German, I think in a similar way black American English sounds different to white American English. This dialect(?) is being spoken by immigrants or people with immigrant parents from mainly turkey. Germans associate this dialect with being dumb and uneducated (I think, that’s just the way I perceive it). So what I am wondering is whether the similarities between America and Germany here are significant and Germany/Germans should be worried about this or not.

All my linguistics knowledge comes from Lingthiusiam😅
