I find exposing stats via system configuration variables a bit unexpected. Not sure if there is any example today that we're following.
Maybe an entry under /sys/kernel/debug would be a better fit?
That way we don't have to commit to a sysctl that might go away if we start charging JIT allocs against memory cgroup quota.
Although that brings up question against which cgroup iptables xt_bpf allocations should be charged? Root cgroup?
