This is somewhat off topic, but are there any common uses for eBPF outside of observability/monitoring? Or is that kind of its whole thing?

Also commonly used for high-performance networking and security use cases, for example https://isovalent.com/blog/post/cilium-netkit-a-new-containe....

Basically anywhere you'd previously need to write a kernel module but now can have user space run arbitrary kernel code that's secure and won't crash the kernel.

You can also now write custom schedulers in eBPF with sched_ext.

Yes, one example: network bandwidth isolation is done more efficiently using ebpf https://netdevconf.info/0x14/pub/papers/55/0x14-paper55-talk...
