That's a fair criticism, you can make the BPF VM more efficient, it's still a comparison of whats there to a JIT though. Even with those improvements, you can get a fairly consistent boost with a JIT, just from turning the loads in to literals. It might not be worth the complexity but if there was a more generic JIT framework such that the platform support was there it is an interesting optimization if you rely upon BPF stuff a lot.
