There are other bars there painted in stripes for the same reason.
There is also a clearly defined path inside the judders bars to enable people caught out or late braking to cross the chicane area without causing damage to the car and rejoining on the other side of the chicane.
But of course they can't get an advantage from it and must redress any place gained.

But its not dangerous UNLESS you try to overtake by going off the circuit and then you are at fault and the author of your own misfortune. You may also be the author of someone else's misfortune.
In that case you will get a penalty.
