You're right, they say so in the FAQ.  And it is the reason I don't use them.

At one point I used PCB Pool (Beta layout) because they could take Eagle files directly.  But sending boards across the ocean isn't so economical.  And Eagle became less and less attractive over time.

My current answer is KiCAD which is open source and somewhat more powerful than Eagle (without the hassles).  Both do Gerbers, but there are also fabs that take the CAD files directly.  OSHPark is the one I've used for my most recent 3 projects, they do nice work.  The color is odd, but what the heck, it still works.
