ib/generator/cleanPublic.js and lib/generator/garbaseCollector.js are no longer called because lib/tasks/file-watcher.js calls lib/utils/triggerOneOffBuild whenever a file is deleted/no longer being generated..

triggerOneOffBuild triggers Trio's build cycle as if trio b was run which rebuilds the public folder so calling cleanPublic is and garbageCollector are no longer required. Remove both and archive their code.
