For instance, I'd rather read:

{ "execute": "info",
   "id" : "32",
   "arguments": ["cpus"]}

I agree.  It's not even expensive.

It's still useful for parsers to easily find the end before parsing.

So declare the JSON terminator to be "}\n" or "}\r\n".  That shouldn't
occur anywhere inside a pretty printed structure.  The internal
closing braces are all followed by a comma.

To be picky, you could have dictionaries pretty printed as

  ...
  'key': {
    'key': {
      'key': {}
    }
  }
}

I think it's either no-delimiter or "\n" or "\r\n".
