I have and found it very suitable for the style of touring I did with it. I have a touring bike that sits mostly unused these days. Since I started packing very light I actually much prefer a road bike. For me I think the point where it started making sense was when I got below 20 pounds base gear weight. It is pretty easy to get to under 20 pounds and still be equipped for camping and cooking. For someone who is willing to go pretty minimal 10 pounds or less is possible.

I do prefer lower gearing than road bikes typically come with though.

Be careful with clamping anything to a CF frame. There are other options though. Racks that are attached at the skewer on the bottom and brake bolt on the top are one way to go.

Personally I don't see the fancy and expensive rack-less bikepacking bags as necessary. I think their advantages are often overstated. They are not always lighter than stuff sacks and a rack and are generally pretty expensive.

If you will be carrying a lot of gear (much over 30 pounds or so) you might consider a trailer.
