BTW, I asked around at DevConf.cz, and nobody I talked with (besides Arnaldo), have used eBPF. The "path to hello world" is quite high. This interface is extremely simple to use, and one doesn't need to install LLVM or other tools to interface with it. I used the analogy, that eBPF is like C, and this is like Bash. One is much easier to get "Hello World!" out than the other. So personally, this is something I know I would use (note, I have never used eBPF either). But if I'm the only one to use this interface then I'll stop here (and not bother with the function graph return interface). If others think this would be helpful, I would ask them to speak up now.
