At that point (and with ES modules) you'd be able to run your TS code directly without any transpilation necessary. I'd love to remove all the build process junk from my projects and have them run quicker.
I've written a few projects as plain ESM JS with JSDoc type annotations and it truly is a joy to bypass build steps. JSDoc type annotations do get annoying as a project grows to a certain size, though.
