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.
