Distinguishing every tense as a distinct entity is usually a matter of methodology. It usually is more practical just to understand the logic behind. I.e. I consider the way I was taught English at school (past indefinite is this, future perfect continuous is that etc) rather inefficient, I could explain the whole system to my past self in a much more intuitive way a lot faster. You also don't need such a huge number of tenses for everyday life. And of course I don't claim I've learnt all the irregular verbs, just a humble portion (and I already can't name a single of them now as years have passed - practice is vital, zero practice = you forget 99.9% of what you've learnt).
