If you are referring to the ASA sharing tutorial docs page, and as it is already stated that you can “use other…back-end technologies to achieve the same goal” and therefore should be able to make this work with NoSQL. This is probably more a feature request, so we would request you to submit Azure User Voice or to give feedback directly on that docs page.
