✅ Viability Checklist

My suggestion meets these guidelines:

• [z] This wouldn't be a breaking change in existing TypeScript/JavaScript code
• [z] This wouldn't change the runtime behavior of existing JavaScript code
• [z] This could be implemented without emitting different JS based on the types of the expressions
• [z] This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
• [z] This feature would agree with the rest of TypeScript's Design Goals.

⭐ Suggestion

📃 Motivating Example

It seems typescript already can provide definition to such files from import statements (on file path string literal), but it doesn't include these files into completion lists (they are actually valid files imports).

js only environments

In js-only projects module augmentations are not possible (until types module providing them is installed)

I think in such cases it makes sense to display files for any extension but for named imports only, but still not sure.

💻 Use Cases

Without it you need to guess path or use 3rd party ide extensions that don't know of module resolution (aliases and so on) such as popular path intellisense. This is annoying and displaying completions and native way to TS is best option for IDEs
