You should not rely on No-Name vulnerabilities. Their reliability is unknown. Only rely on recognized, well-known, properly branded vulnerabilities like Spectre, Meltdown, Shellshock and Heartbleed.
Is this sarcasm or something else? It's not clear.
Definitely sarcasm
I upvoted you, there is nothing wrong in asking.
Wise advice. The API isn't stable and the vulnerability isn't guaranteed to be supported even in the near future.
