I did. There's absolutely nothing interesting in it.

Your argument about two-way communication is just ranting. The fact is, you want solid and stable ABIs for kernels, and you don't want some malleable and complex interface.

We have a runtime JIT with binary translation in the kernel already. It's called ebpf, and it's in quite active use for its intended purpose.

And it has absolutely no bearing on this thing, or on other parts of the kernel.

Anybody who thinks that binary translation is a replacement for static code generation is just living in their own dream world. It's just a tool in a toolbox of things, and has its own serious problems.
