There are certain moments which are not that important and can be ignored as just gags or unimportant reveals. And in isolation the confirmation of Zoro having CoC might seem just like that.
But if we take into account the last few arcs there seems to be a trend where we get seemingly unbeatable opponents and then we get a way to defeat them.
Until Katakuri and BM (in post TS) there wasn't any such opponent which required some specific technique or condition to be defeated. Tbh the Kata situation does not fully qualify since FS itself was not a requirement to defeat Kata but it was a skill which was learned by Luffy. And for BM the portrait needed to be destroyed for her impenetrable Iron Balloon defense to be deactivated.
Then in Wano we had Kaidos invincibility which needed ID and Enma. We got a specific condition for Kings flame off too. However for both opponents the requirement turned out to be ACoC.
Then in EH we again get King Jrs and they seemed unbeatable but were neutralised with the bubble gun (anime showed Zoro beating two but lets stick to manga panels for now). In EH we also got introduced to the seeming immortality of the Gorosei and there seemed to be no answer and the final savior was JBs CoC blast which sent them back and allowed the escape.
Now in Elbaf we again have these immortal HKs, Gorosei and Imu who keep regening. There are two instnaces where the regen has been shown to be slowed down, Gaban vs Sommers and Rocks vs Garling. We get the problem even earlier and have the SHs Jinbe and Chopper trying to figure out how to beat this infinite regen. Then we have Gabans showing and him commenting on how CoC might be the solution. This is reinforced in the FB when Garling is taking longer to regen and then is shown defeated.
However in case of Imu/Saturn an extreme amount of CoC doesn't seem to be the solution since there was no indication of any sort of slow down.
So why was CoC focused on if isn't the solution. Why were both Zoro and Loki shown to have the power but not realise it or know its nature/name. Why Gaban told Luffy to focus on it? The FB is not finished yet and Imus goals in GV were not accomplished since at least BB survived.
To me it seems like another one of the seeming invincibility and specific conditions combo like BM and Kata and Kaido and King. There is a technique for the counter like against Kata and Kaido for the slow regen effect and there is a specific condition for the counter like BM and King for the Imu regen (the problems as they seemed at that point in time). I think the real body in the abyss needs to be targeted.
If we look at the situation I think it is easier to describe the Zoro confirmation as him learning a skill like he did against Mr.1 (haki) and recently against King (ACoC). But like Zoro said he needed to be able to use the haki skill whenever required even after beating Mr.1 but he didn't know what it really was and could not use it against future Logia opponents like Enel and the sword rusting guy. Here Zoro has ACoC the answer to the HKs/Gorosei but now has knowledge about the skill and can counter the HKs/Gorosei (Logia).
