When I oopsie in server-side software, I roll it back, hopefully users never see it. When you oopsie client-side software it’s far more likely that users see it and resolution takes order days, not order minutes.
As I am a coward, I only work server-side 🙃
I read somewhere that the armor distributes blaster bolt shock through it so all the Stormtroopers get knocked unconscious. They don’t die, otherwise they may as well not wear it at all as they fall over after one blaster bolt.
But as with everything in Star Wars lore, that’s probably a desperate retcon.
