For a review, I'd need users of this functionality. In this case, a master driver and probably a sensor driver. Can any regular I2C master talk to these devices if they support talking to addresses 0x00-0x7f? My first impression is that using a class is not the proper approach because classes were used to limit access to devices, not to extend. However, I'd need to see more code to check if that holds true.
