Now that we are OT: it depends on the hand. If I have a small singleton spades I open AKxx AKxx Axxx x 1♣ and after my partner’s 1♠ my bid will be 2♥. If I have A or K of spades, I would answer 2NT. Anyway, the 4441 is the weak point of most simple natural systems.
Not for me - I play a "stone age" natural system where an opening (suit) bid at the one level shows my lowest ranking 4-card suit etc.
