Imagine the powerscaling if Page One and Ulti can actually withstand Big Mom for a bit, but then lose to Nami and Usopp.
I think its 100% all about recovery. My hope is that due to Udon and the fact that Wano is known for Kairoseki masonry and carving, when they are taken out, someone creates makeshift Kairoseki prisons that prevent them from escaping.
I don't expect literally any one Zoan to stay down this arc. They need to be captured after being defeated (cause unlikely Oda kills anyway, I guess except maybe Kaido or Orochi)
I honestly expect Page 1 to recover, people take note of it, and maybe if Chopper fights him and Nami/Usopp tag Ulti, they capture the first 2 executives, then pass it on to the rest of the fights.
