+          The `#ask` method has been present in cucumber for a while, but its purpose outside of cucumber is
+          questionable. It is being deprecated and will be removed in a future version (Targeting v12).
+
+          If you are using it in your own code, you should remove the dependency on it and implement your own version
+          of it. If you are using it in a step definition, you should consider whether that is really necessary and
+          use either a conditional waiter or use a tag so that the scenario doesn't automatically run in a CI
+          environment where there is no operator to answer the question.
