I think it would be awesome to reuse the kernel's BPF engine
with its C backend for this in the way that Alexei has started
in its original set; surely there's a lot of work that still
needs to be addressed, but it would allow long-term for just
having that engine to maintain, and also to exploit its
flexibility and speed (JIT) where we can.
