Haki is complete bullshit now anyway, just like trying to powerscale Loda's mess or crafting theories for a story or its lore whose author is only determine to contradict itself as much as possible. The man refuses to take advise from people who aren't bootlickers and his editors are just crying buttkissers.
Haki also took away what made fights interesting prior to the timeskip, trying to defeat the impossible villain by finding his weakness or using a strategy to use their own powers against them. Now its just "my haki can beat your haki'.
