For some reason, the dump fails to pull in the new routes when a module is installed and so simply rewrites the same values. If one later goes in and manually re-dumps the file, it properly loads the exposed js routes for the newly installed module. I need some ideas on how to fix that.
You can use I18nLoader::ROUTING_PREFIX instead.
