Yeah - it's weaker too. I promise you. Give a good pull to a swatch or clipping sometime. It's much weaker than most suiting fabrics.
Not that there isn't a place for these fabrics, I'm perfectly delighted with the few suits I have made with them. And luxury does not by any means imply durability.
Just that they seem to be getting a lot of promotion these days in the luxury ready to wear market and I hope people understand what they are getting. It's not for everyone, or everywhere.
