That's a lot of ppl point. Sanji is important but has not seemed that way since Dressosa. & he wasn't stellar in WCI. ODA owes Sanji A lot....
Since the brief clash with Vergo which shows Sanji was weaker than his foe. Sanji does not get to redeem his pride with the fans, he gets a brief notable save the Day against Doffy but its short lived, he gets caught and almost loses. Which isn't to be held against Sanji, Doffy was the main Villain. But after Sanji is depressive during WCI, he never fights off Bege or Pekoms at Zou. & Oda doesn't have Sanji defeat anyone noteworthy from BMP Ministers. Bobbin was a 100k pirate, that's more Fishman island type fodder. He barely saves Luffy getting help from his family he hates....Fast foward to Wano, Oda is off screening Sanji taking the opportunity to defeat a Beast Pirate member, & shows his RS....
ODA needs to stop the shit, & give Sanji some more respect.
