I was mostly thinking about complex configurations where writing a JSON
config would be simpler than adding a lot of command line options.
Something like dumping a JSON file and allowing to refer to a JSON file
as you suggested could be useful; but then, those very complex use
cases are probably already covered by editing the config file directly.
Not sure if it is worth the effort; maybe just leave it as it is for
now.
