Programming in eBPF directly is incredibly hard, the same as coding in v8 bytecode. But no one codes in v8: they code in JavaScript, or often a framework on top of JavaScript (jQuery, Angular, React, etc). People will use it and code in it via frameworks. What is an example of eBPF tracing? It's the same with eBPF.
