Do any rappers freestyle straight off the dome anymore?

Just asking cuz i noticed that two of Lil Wayne's freestyle verses are from "live from the 504" and "Eat You Alive". Then Wiz Khalifa's BET Cypher freestyle verse from "The Checkpoint"? It seems to me, that rappers dont spit off the dome anymore, they just recycled used lines and make us think they're straight off the dome
