I imagine the window still shatters but keeps together instead of spraying glass everywhere.

Similarly to glass with an embedded wire mesh.

Exactly this. In fact, it’s the same protection I have now at home in a couple of roof windows. Not because I expect attacks, but because I’ve got one more floor above and I want some safety in case something heavy and loose falls down during a storm.

The glass is gone anyways, but the goal is never to save the glass (that’s impossible, I guess) but to dramatically minimize the risk of personal injury.
