That shit only came up DURING Wano. Oda had no pre-existing reason to include that besides wanting to make Shiryu invisible (which could have been done after or in any other way).
I agree that Moriah was wasted so hard. The dude was mindbroken so hard by Kaido that he became a fat worthless fuck and had more of a reason than anyone to show up to defeat him (besides his DF just naturally being an excuse to give anyone a power up on demand).
Despite being mocked and thrown out at the end of pre TS for being weak and despite not seeing him at all post TS we finally do see him during Wano, on a completely different island, still fat, just to learn that one of his last living crewmembers was killed while the murderers laugh in his face about it.
Thanks Oda.
