I get the same benefits from my other tooling. Lint and type inference provide real-time feedback similar to TypeScript, and TDD gives me continuous test feedback every time I hit save. That's the zero point on the ROI scale, and while I admit that well annotated TypeScript code does it a little better, it's not better enough to justify the cost.

If you haven't already written an article about your tooling, I think a practical guide would be well received. Not many users are aware of thees tools, which is why TypeScript is so amazing. I don't think most TS users use it because they like to annotate things, they use it because the autocomplete and editor integrations.
