Client and ClientManager deal with both 'dehydrated' channels/networks (ie. directly from JSON configuration) and the 'rehydrated' ones (classes, with socket objects, message arrays, etc.). However, because their attributes are similar, both types were used interchangeably, which becomes an issue when splitting Client's configuration loading into smaller methods.
