Yes, it has a few APIs of its own. I merely think they are negligible in this discussion because they only provide a minimal superset over Node.js’s own APIs and are also very minimal compared to what Deno provides.
I’ve updated my post to mention “noteworthy” APIs.
I agree the Linux kernel is just fine. But that’s only because despite the security risks of C, there’s no viable alternative kernel.
But development doesn’t stand still, so either Linux catches up, or gets replaced when a viable alternative arrives. Thankfully Linus sees the problem, so they’re working to make the kernel viable a while longer, but I also agree with the person you replied to that this work could definitely use a bit more help.
