The main component of wano arc so far isn't yonkou or shs alliance or samurais but oden.
He got consistent hype and has been linked with all sub plots of wano. It's to be noted that oden is also important in grand scheme of things like raftel,pg, ancient civilization and final war.
So his flashbacks is much more important than anything as of now. Not only for giving us crucial info and give us some emotional connection to wano war but also to understand bigger plots of one piece.
Skipping it for the sake of war is totally unjustified claim from narrative and readers point of view
