I'm not so sure. You're supposed to give it 2 turns after the drum contacts the tire. That's never felt like that much pressure to me. And you've got about 10 pounds of pressure from gravity, that isn't on the wheel in the trainer stand.
Additionally the pressure goes down as it sits there, with the tire gradually losing air.

I am using special skewers that came with the trainer.
You're not going to damage the skewer by leaving it in the trainer. In fact you're going to do more cosmetic damage to the skewer taking it on and off the stand each time, rather than leaving it sit.
Besides why would would you care if the trainer skewer gets scratched?
And the only way you're going to permanently flat spot the tire is leaving it sit in the trainer unused for a long time. Leaving it mounted on the trainer for a winter, and pedaliing it from time to time is not going to damage the tire, other than wearing it out. I can verify that from personal experience.
