I think like a lot of BSD people I felt lua inside the machine was bloat. More a religious perspective than reality, given it meant a kernel could do things like manipulate variant data without having to be hard coded. And eBPF has shown in Linux kernels the power of scripting inside the os.

This is the first user space lua code in BSD I could imagine actually using. I suppose I deserve to be told what other things use flua I haven't realised.
