The novel isn't set on a time period where we can learn new things about the worldbuilding, Zoro's powers, or his lore (Zoro himself doesn't even know about his ancestry even now), so what it has going for it is "Zoro" and potentially "a good script". If it has the later then that's good enough.
If we get to see Arashi's death it'll be interesting. It's not that bad for Oda to show that in a novel, it's actually more special than ham-fisting it in the background of Wano.
You may say I'm coping for what I'm about to say, but it's also very likely we will still learn more about Ryuma in the future of the manga. Oda skipped over the most important time of Kaido's backstory and that was no coincidence, he considered Wano was not an important enough arc to reveal too much about Rocks. There'll be a time to learn about them just like there will be a time to learn more about Ryuma when we learn more about the world's history, the Gorosei's or Mihawk's.
This manga just takes too long.
