The intended context of the question, which admittedly could be more clear-- is for a data product that could be used for any data. Take Cockroach DB for example, which already has python integration ( https://www.cockroachlabs.com/blog/sample-app-python-and-coc... )
With platforms like DataBricks and Airflow that are heavily inclined towards python, it feels somewhat unavoidable to need to offer a way to access the product via "import" in python.
So the question is: in that scenario, could a commercial product still survive-- or even thrive-- without doing so?
