Because aggregate.formula has a formula argument but the generic
has an x argument neither of these work:

  mtcars |> aggregate(x = mpg ~ cyl, FUN = mean)
  mtcars |> aggregate(formula = mpg ~ cyl, FUN = mean)

This does work:

  mtcars |> stats:::aggregate.formula(formula = mpg ~ cyl, FUN = mean)

Suggest that aggregate.formula be exported.
