FYI, I am actively working on this feature in #939.

@rohanPAnkam sorry that we raced on this. I just merged #939. As you can see from the PR body, I took a slightly different approach than that of the TypeScript CLI, but as noted, I believe it is also more robust to things like concurrent writes.

Please try it out and I would be interested in enhancements for this feature.
