Why do think any of those labels are critically important? They are entirely derived from human desire to understand, process, and define a taxonomy for language. There is absolutely no reason to think that they are inherently necessary to achieve the goal or high fidelity translation (or anything else in this domain). Similarly they might be meaningful but inferred naturally through the learning process. If your goal is to map machine learning processes to established dogma, this makes sense; if it is just to build an effective learning machine that solves an extant problem, then it's not.
