Maybe not completely. There were several references to AOS in Wandavision. For example, the Hydra Soap ad is believed to be a nod to the AOS Framework story line where Coulson was sure that Hydra was using soap to mess with everyone’s memories. Also, the Darkhold from AOS which was taken to the dark dimension by Ghost Rider, was returned from there by Morgan Le Fay in the Runaways series. Somehow, Agnes Harkness took possession of it after that and it appeared prominently in Wandavision.
