Why don't you just make the transformer API stable, public, and let the community do the hard part? There's plenty of us that have experimental transformers doing all sorts of fun things, these are problems that can be solved external to TS.
I've got a fully functional compile-time dependency injection container that I've been sitting on for literal years because the transformer API isn't public.
^^^ Please do this. I'm completely ok with "using transformers voids your nonexistent warranty" and the community can deal with transformer API churn. Exposing the API makes it easier to adopt those community solutions, versus me needing to explain to teammates why I switched all the `tsc` invocations to `ttsc` and promise it's not that sketchy.
