Yes, I use TypeScript types very idiomatically and have received very positive feedback on my TypeScript code. But just running `tsc` takes >10 seconds on a relatively small project, and IDE support is becoming proportionately slow, e.g. hovering over anything to show its type often takes 5-10 seconds before VS Code will actually have something to show me. It's becoming painful, and that feature which I once heavily relied on has become nearly useless to me.
