Currently the PCB files are provided in gerber file format which are only used as input for manufacturing. These are generated output, not actual reasonably easy to modify original source files. If I want to go round off some corners (for example) it's really not worth the sheer amount of effort that would be needed to modify them.
Native Eagle, Altium, KiCad, etc. files would be much easier to access. Until that happens, I wouldn't be exactly referring to this as "open".
