controller.js is handled by ember/order-in-routes rules when using new MU architecture

I believe the error happens somewhere here https://github.com/ember-cli/eslint-plugin-ember/blob/master/lib/utils/ember.js#L110 because in MU (https://github.com/emberjs/rfcs/blob/master/text/0143-module-unification.md) everything lives in routes folder that is why the second clause is always true
