To help lazy developers, they don't have to dig up the datasheet to see what address their chip is at? Well, I guess they might have to do that anyway to see what address out of these is selected with the address select pin. I thought it would be neat to have all the possible addresses listed here, and the developer could pick the correct one for his/her board file. Or in the case where he is not sure about the state of the address select pin, maybe even try them all.
If you're going to do this a comment in the driver describing what addresses correspond to which device configurations - having it as a bunch of #defines in the code is less discoverable and still requires users to look up in the datasheet to see which address the device actually has.
