Amazon's Kindle isn't just an e-reader that competes with the iPad; it's also an eBook format. You can read Kindle books on the iPad using Amazon's Kindle app. Kindle eBooks are a modified version of the Mobipocket file format and use the .AZW file extension.
However, just like AZW, you can't upload an AZW3 file format at the KDP. You can certainly make a file in that format, and side-load it to your own Kindle device, but you can't publish it. Obviously, that format, then, lacks utility. Fine for personal use, but useless for publishing.
