bpf load and unload as just another tracepoint to throw into a set of events that are monitored. As mentioned before auditing the loads and unloads is one example.
And that brings up another comment: Why are you adding a PERF_RECORD_* rather than a tracepoint? From what I can see the PERF_RECORD_BPF_EVENT definition does not include the who is loading / unloading a bpf program. That is important information as well.
