> Slacking around SQL snippets, schlepping around CSVs, devs having minor inconsistencies when running a bunch of ad-hoc queries: problems for sure, but not major ones for a small company.

This is a general theme: it is hard to fight "good enough". Even in a big-enough company, a competent engineer will have a good enough way to manage queries, while incompetent ones won't care. In the end, very few people will want to pay for such service, or even want to learn such service.
