Passing arrayLimit as 0 to qs@6.14.1 parses arrays as objects with indexes instead of arrays (lib/types/urlencoded.js:99). Since extended is false by default, our default behaviour has changed.

There's also a failing test

  1) bodyParser.urlencoded()
       with extended option
         when false
           should parse multiple key instances:
     Error: expected '{"user":["Tobi","Loki"]}' response body, got '{"user":{"0":"Tobi","1":"Loki"}}'
