Documentation: `any2stringadd` being blacklisted is not documented

Minimized code

object App extends App {
  (??? : Any) + 1
}

Output

value + is not a member of Any, but could be made available as an extension method.

One of the following imports might make progress towards fixing the problem:

  import math.Fractional.Implicits.infixFractionalOps
  import math.Integral.Implicits.infixIntegralOps
  import math.Numeric.Implicits.infixNumericOps

Expectation

Expected to match Scala 2 behavior, however it seems the change is intentional, but undocumented:
