I did not say that. I think it is a good thing to do thing properly. File resolution is pretty complex (too complex) in Node/TSC. I would like others tools to support native .ts imports and translate automatically to .js on code emitting. However, it is not going to happen in the short and medium terms.

Using a fallback to .ts files when importing .js files is a minor and straightforward addition to file resolution. And this is a big gain in terms of interoperability with others tools.
