monkey patch to pass some options (e.g. create :create_additions for couch_potato) to the json adapter

multi_json.rb

# config/initializers/multi_json.rb
+ MultiJson.default_options = { create_additions: true }

# lib/gem_ext/multi_json/multi_json.rb
  module MultiJson
    # Decode a JSON string into Ruby.
    #
    # <b>Options</b>
    #
    # <tt>:symbolize_keys</tt> :: If true, will use symbols instead of strings for the keys.
    # <tt>:adapter</tt> :: If set, the selected engine will be used just for the call.
    def load(string, options={})
+     options = default_options.merge(options)
      adapter = current_adapter(options)
      begin
        adapter.load(string, options)
      rescue adapter::ParseError => exception
        raise LoadError.new(exception.message, exception.backtrace, string)
      end
    end
    # :nodoc:
    alias :decode :load
  end

But wouldn't this always enable create_additions, also for requests that come from untrusted web clients?
