And as a counter example here you have openbsd "we are going to install a bgp daemon on every single device, because you never know when you may need one"

I am not complaining, I like the feeling that I could single handedly rebuild the internet using only what is found in an openbsd base install. But wow, considering the size there is a lot in there. They definitely punch above their weight.

But Bluetooth is basically a giant blast of security vulnerabilities. On the consumer side, yes, it's a big subsystem to drop, but on the server side, it's a little bit different!

I'm not an OpenBSD expert, but seems like you should be able to pass BT through USB and then do that in a subsystem or an isolated environment like a VM.
