It's like whatever now.
Zoro and Luffy are destined to beat colossal enemies next.
+ Oda set himself up for failure with this writing anyway. They are already knocking on the doors of two Yonko so what is there left after? Only Admirals? Gorosei? Another Crew?
Sure, Oda wants to prepare them for the final route but the execution was poor anyway and not only here. Almost every time.

Also Zoro is going to be heavily injured the next arc due to Mink medicine so there's another Yonko level person waiting for him, BB, maybe an admiral, maybe BM in Elbaf
With Zoro being injured it gives Oda free range to do whatever he wants and keep the expectation, because everyone fought Kaido and was damaging him so in theory Luffy never "defeated" kaido in an all out 1v1
