I feel like this may need to be reiterated, but Jerza did not need chapter 545 to become canon. They have been canon 200-300 chapters prior to this one. Was their ending what I would have decided? No. Was I happy with it? Not exactly. But they’ve been canon for ages and to say they needed to become canon in the final chapter, especially compared to other ships who were banking on this chapter to confirm their relationships, is just asinine.
