Nub could absolutely support a config file and use it to set NODE_OPTIONS or flags in the node child process. There's no reason to throw out the baby with the bathwater due to DX concerns like this. That's a key part of the concept Nub is trying to prove. (To be clear I'm quite content to conform to Node's no-config-file policy at the moment.)
Tangential but this also drives me absolutely nuts. If I have to see `"//": "some comment"` one more time I'm gonna lose it.
