Looking at the file format limitations [1], it doesn't seem like a good fit for an alternative to ODT files. (A cursory judgment based solely on this wiki page has me wondering if they are using the best data structure for an Index, but again, very cursory.)
A question is why you would want to replace the current ODT format? "Just" a zipped up file tree of XML documents and image assets is a pretty robust format choice. There are unzip programs on almost every platform. XML isn't always everyone's favorite markup language, but it's well supported by almost every language ecosystem, and still roughly okay to humanly eyeball if needed. The relative inefficiencies of the textual encoding and verbosity of XML are directly suited for compression efficiency of a Zip file. For most trade-offs of a document file, it's a somewhat resilient option,
