Yeah, so the principle is the following: the main configuration option for it is 
BPF_SYSCALL. The BPF_EVENTS is an internal detail, always enabled when possible, 
and we make it so that if the BPF syscall is enabled, we'll enable the perf 
integration if all the must-have components are in place:

So this is intentional.

Unless your suggestion is to also enable it when neither KPROBE_EVENT nor 
UPROBE_EVENT are defined. Does that make sense?

Thanks,
