The premium bag makers do not yet offer it(kinda like they were years behind on entering the quilt market), but with made to order quilts it's usually an option. So if you do want it, you can get it.
Both my quilts use 850 Hyperdry goose down, as that was the option at the time vs regular 900 fill. It's not that often that I get to see where the treated down makes a notable difference(and sometimes what difference there is may well be due to the shell material), but the few times I have were when it really mattered, so I'm pretty sold on it. Options are good...
