yes. Have a prototype, but it needs a bit more cleanup.

Here's [1] actually some code snippet for user space
Extended BPF (or 64-bit BPF) is an instruction set to
create safe dynamically loadable filters that can call fixed set
of kernel functions and take generic bpf_context as an input.
BPF filter is a glue between kernel functions and bpf_context.
Different kernel subsystems can define their own set
