Yup. It's a bonus. If you want to know why a corporate entity makes a decision then follow the money. When it comes to Kindle, that money trail leads me to the Amazon Newsstand and comiXology. But why would Amazon need a new format when KF8 already covers the necessary features and then some?
The answer is file size. Files with raster content are big. They're orders of magnitude larger than text ebooks. Large files on small devices is a problem. The solution is to split large files into smaller pieces. ePub addressed this before it became a problem by being a multi-file archive format from the start. Of course, Amazon won't adopt ePub so they had to invent their own multi-file format.
Enter KFX.
