My understanding is that [gpio] is based on wiringPi https://projects.drogon.net/raspberry-pi/wiringpi/ My understanding also is that wiringPi is the best of the bunch (in C, most direct access to the various pins, well written, most widely made use of, etc.) There's a couple of nice utilities in wiringPi that could be extra objects for a PiLib, including a nice gpio swiss-army-knife type thing as well as i2c control.
If anyone's got the skills and some time (I don't have either currently) it could be a really useful addition for Pi and Pd.
