   As the user who reported the bug this PR is solving, I'd like to very succintly add my opinion.
   
   I personally **strongly** believe that `as.data.frame()` should return a `data.frame`. Plain and simple. That's just what would be intuitively expected. If I cast any object with `as.X()` then I expect the result to be exactly `X`, not a clever derivation/subclass of `X`. If I want a tibble, then I'd use for `as.tibble()`.
   
   Having `as.data.frame(x)` and `as.data.frame(as.data.frame(x))` return different types feels very wrong.
