Depends on D123655 With this patch, the MessageHandler can immediately check if a command is implemented by the modules, and therefore reject as early as possible. This is implemented via a checkCommand method on MessageHandler. Other required changes: - ModuleRegistry now owns the logic to import BiDi modules. - ModuleCache exposes a `getAllModuleClasses` to get all the relevant modules for a moduleName+destination pair. Error messages have been improved and are verified with a dedicated test Differential Revision: https://phabricator.services.mozilla.com/D123655
