Uh, yes, because then this scene in Chapter 868 does NOT make sense:
Big Mom not having Giants would be a random plot point with zero payoff if she found out she ate the children and Caramel on her own. A giant needs to tell her why they hate her. Its what makes her character come full circle. If Streusen told her or she herself remembered (which she cant judging by the images I just linked), then there would be NO reason for the Elbaf plotline in relation to her character.
You could have left that part out and Elbaf could have hated her for killing one of the Giant leaders, thats it. Oda does NOT leave plot points unanswered.
Edit: Plus, you have to remember that we have a cover story with Lola and Chiffon going on RIGHT NOW. There is a clear payoff happening where LinLin will see her daughters again and either try and blame Lola for not marrying Loki or realizing the whole mess was initially her fault to begin with.
