BPF is completely production safe. So there is no way for a BPF program to crash the kernel, introduce significant performance latency, or have any side effects on the kernel/user space. Obviously, kernel modules have none of those properties.
Also, BPF has been around for almost 30 years, and you're likely using it. tcpdump is basically just a BPF bytecode frontend, for example.
