It isn't required for safety reasons - by which I mean not to reach internationally accepted safety standards. If you want to increase the level of safety beyond that, then that is fine but it shouldn't be enshrined in law by regulators as they have no basis for such a change.
As I said before, far better to concentrate on stopping all this crashery rather than fretting too much about escapability under a very narrow set of conditions which may not be repeated for a very long time (last time I guess was cormorant A, 22 years ago).
