One thing that would make this really useful is a frontend widget that abstracts away many of the common complexities that arise and right now still have to be learned by everyone using this API. E.g. learning how to correctly construct recurring events and implementing a minimal UI for it would still be a pain even with this API. Algolia and their instantsearch.js (and React, etc.) packages are a great example for that where you get the faceting display logic for free.
