Honestly never felt like Carrot was being forced on us more than her relevance could justify. In her intro arc in Zou she, along with Wanda, was pretty much just the SHs guide while the new setting was unraveled. There wasn't any particular focus on her and her panel time felt proportional to her role.
She has a more prominent role in WCI but still really didn't take panel time away from any of the important stuff. I would say her presence actually added impact to one of the big moments with Pedro's sacrifice. The highlight for her obviously ended up being the sulong scene which I personally found to be not only a cool introduction to the sulong concept but also a genuinely pretty cool scene. Outside of all of that she just fit well with the usual dynamics and hijinks of the crew so at worst her presence was harmless.
And that's pretty much it tbh. She barely has any panel time in Wano so don't see how one could argue she took up undeserved focus here. In fact I would have appreciated a bit more context into the decision to suddenly make her the ruler of Zou, it felt really rushed and nonsensical... In any case her and Pedro were probably my favorites of the SHs new allies in the Yonko saga. I grew tired of the scabbards as they started developing into one dimensional Oden worshippers (not much of a fan of that character in the first place) and Yamato only made that worse....
