I find this somewhat amusing given one of the primary use cases of eBPF is measuring performance

  There's plenty other applications. Network routing can be implemented in (e)bpf. It's even the original use case. But there's also the LSM based on ebpf, there's a user space scheduler (Google iirc), seccomp and some cgroup filters can be done in bpf... It's the Lua of the kernel at this point. Provides a lot of extension points.

    sched-ext is meta, Google have something else but less open i believe. https://github.com/sched-ext/scx/blob/main/OVERVIEW.md https://github.com/sched-ext/scx/blob/main/OVERVIEW.md
