Elbaf will definitively prove Shanks and Mihawk old news for Luffy and Zoro
You can argue they proved that when they beat Kaido and King doing things more impressive than Shanks and Mihawk have ever done
Tho you could argue due to their egghead showings that they were as they seemed due to not defeating the seraphim, Lucci, or Kizaru
Luffy has already proven himself to be emperor or top tier level in wano. Both Luffy and Shanks being actual emperors with emperor level crews
Zoro has already proven himself to be warlord or commander level in wano. Both Zoro and Mihawk being the 1yc of emperor crews
When Luffy and Zoro fully understand and master their onigashima power ups if it was arguable before elbaf post elbaf it will be undeniable that they are out of Shanks and Mihawks league
They will soon be fighting and soloing gods making Shanks and Mihawk even more irrelevant
