I'm guessing with the proper gear, snapcaps or something to drop the hammer on, they would be fine. I'm not sure what the issue is with the trigger return spring.That's surprising to me, especially given the surging popularity of the brand. Given that I've not heard about it, I speculate that those who actually use them hard are amenable to fixing them with aftermarket parts and probably most don't use them or don't dry fire enough for it to be an issue.
I used to own a 1990s vintage CZ 75B. It was among the most reliable pistols I ever owned, but I couldn't reach the trigger or thumb safety properly, so I sold it. I would hesitate to buy another with this new information. You should be able to dry fire a modern centerfire pistol without adverse effects.
