Interesting. But if tuning parameters to their best values were easy, shouldn't the kernel just do that in the first place?

It depends on workload. This tool generates recommended config for that specific machine workload. App Nodes can have completely different recommendations vs Database Nodes. It will be completely different for Workstation.

Sure, but the kernel could just do the same. Of course the kernel is already too big. Is BPF the right level to make it more modular? Just thinking, I don't think I have the answer.
