Do you have any plan to add a visual interface? Unfortunately many analysts I work with are not really capable in SQL, or don't fully grok SQL features.
Also, how you plan on creating a moat against cloud companies putting the functionality of your project in their own proprietary solutions? For example, in Azure you can already use the Azure Data Lake stack of ADL Storage + Analytics + Data Factory to do what you are doing. These have IDE integrations, CICD integrationos, git integrations, are first class citizens in their cloud interfaces, etc.
