Also consider that bpf_lsm hooks have a way to get cgroup-id without
being explicitly scoped. So the bpf program can be made cgroup aware.
It's just not as convenient as attaching a prog to cgroup+hook at once.
For prototyping the existing bpf_lsm facility should be enough.
So please try to follow this route and please share more details about
the use case.
