Gonna hit y'all with some harsh red pills.
Zoro is a character designed purely to draw in chuuni readers who would naturally gravitate to edgier material like Naruto. Oda never intended for Zoro or his "arc" to matter. Why is it his backstory is the least developed of all the Strawhats? Why is it he hasn't grown as a character besides shallow pretenses like "muh captain?" It's because he's just there to do cool shit and placate the demo he was designed to appeal to. With the introduction of characters like Trafalgar Law, Eustass Kid, Zoro's necessity as the edgelord character has deteriorated. Ultimately, Zoro is the most expendable Strawhat for Luffy will gain allies that are just as strong, if not stronger than Zoro is, and they have defined arcs that will reach a satisfying conclusion through combat, whereas Zoro's is just "getting stronger." That would be nice, but Zoro's strength relation to the rest of the story is undefined and unimportant, so it never really matters if he gets stronger. No one ever mentions the people Zoro defeated, nor does it ever play a factor in the story in a significant way.
His most defining moment in the story was even fittingly described when he uttered the words "nothing happened." For nothing narratively engaging or rewarding came about it. Kuma was never planning on killing Luffy either, and would've just as easily bullshitted an excuse to the World Government like he did in canon.
It seemed like Oda was finally going to give narrative weight to the weightless swordsman in Wano, but even that was merely to give him a new sword. A sword who's rules and conditions will not be consistent with Zoro's use of it, as Oden isn't a brainless power fantasy like Zoro, and is a character with deep importance to the story of One Piece. Oh sure, Zoro's gonna make his black, but that's to sell him up as the edgy character because black is cool and edgy, kids. Please buy Enma Zoro fig at a store near you.
