With Kiringham getting swift diffed, like I’ve been banging on for the longest I think the opponents for the wings this arc is going to be the Gorosei (Nasujuro and Mars most likely)
Oda needed to establish that Sanji can hurt the holy knights which he’s done with this chapter.
Adequate challenge for wings now is an opponent that can actual test their CoC potency & skills and CoC barrier is needed for that.
on the topic of Kiringham though, quite like the way Oda handled it tbh. No time wasted on fodder & also flexes Sanji’s tact (could be that Nami and others were also involved in some capacity but we’ll see) with regards to completely immobilizing the holy knights ^^
