class TopLevelFormatter(logging.Filter): (source)
Keep only top level loggers's name (direct children from root) from records. This filter will replace Scrapy loggers' names with 'scrapy'. This mimics the old Scrapy log behaviour and helps shortening long names. Since it can't be set for just one logger (it won't propagate for its children), it's going to be set in the root handler, with a parametrized ``loggers`` list where it should act.
