Well yeah, it's not everyday English maybe but it's still English. By that I mean that those are examples of which and how many of the rules in the system can be broken or let's say - creatively interpreted and still fit in that system.

"bad english" by expert native speakers is different than "bad english" from poor native speakers is different than "bad english" from still-learning non-speakers. IMO the first two both benefit your understanding of the language and help with reading comprehension because they expand your personal knowledge base of how many ways you can convey the same meaning in English with different words, order, grammar, etc and that is crucial for a flexible language like English.

But your reply reminded me of a friend that's very good with languages but only languages that have a rigid structure - he's from the UK but he struggles with English yet he's amazing in German and Chinese and several others I don't remember.
