It can trigger it yes, and it is destructive to the saw blade and safety device, and can ruin the clean cut of the piece, though may or may not ruin it entirely. Good saw blades aren't cheap, and neither is the safety device. I'm unsure of what wear and tear it has on the motor itself, they can at least endure a few triggers for certain and I doubt it's "good for it" but unless you're doing it frequently I also doubt it likely to ruin the device itself but admittedly am not sure about that.
And to be clear, it's well worth it IMO. Of all the tools I have in my shop, the Table Saw is easily the most dangerous. If I had long hair the Lathe would give it a good run for it's money though. I refuse to use a table saw without a sawstop (or similar safety break). The one I have and others I've used all have a key to insert to disable the safety device If need be.
My dad was a machinist when he was younger. My siblings and I grew up with a well-equipped home shop, including a table saw, a drill press, a milling machine, and my dad's pride and joy: a two ton metal lathe. He drilled into us the importance of safety for all the tools, but the most vivid lesson was the story about the drill press: When he began his apprenticeship, he noticed a large photo on the wall of the shop of a long pale stringy thing. He asked what it was. It was a tendon which had been yanked out of the arm of someone whose hand got caught in a drill press. I still think about that whenever I use a drill press.
