Not really, though some writers undoubtedly still think so. The closest anyone came to saying that was in Uncanny Avengers when she said she could do it again given a sufficiently large power source, and she used Wonder Man's ionic energy to do a mass teleportation spell. But that is based on the idea that she can't do something huge like that without being amped up from outside.
The first time we saw Wanda really get amped like that was when she accidentally tapped into the DC universe's Chaos Magic in JLA/Avengers, which is why there's a fan theory that that was the Life Force. Of course it can never be canon.
