J.The extension is ".tf8", and the format is called "8-Byte TIFF".
Breaking the file-extention is imho not alternative 1. The file extention should still be .tif or .tiff
Unless you can get every application to adopt the new library, and every user to upgrade their applications... using the same extension will just create a lot of confusion ("it's a TIFF file, why can't Photoshop 3 read it?").
Changing the extension (and Macintosh file type) will remove that confusion -- communicating that it is a new file type and won't be compatible with older readers. This will also give software vendors an obvious way to indicate compatibility with the modified format.
