Dai Davies (ARB Chief Test Pilot) view from "Handling the Big Jets"
"It is wrong in princple to allow a swept wing a/c to suffer significant angles of sideslip"
The difference in apparent airflow between leading and trailing wings can cause a spin at low speeds.
Large sideslip angles via abrupt inputs can also cause engine surge/stall.
A couple of degrees in ground effect is not a major issue.
