Option for auto-import to prefer direct exports over re-exports

✅ Viability Checklist

My suggestion meets these guidelines:

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

⭐ Suggestion

Some libraries provide the ability to import modules using sub-path module specifiers (import {SubModule} from "@scope/library/submodule", as well as re-exporting the module at top level (import {SubModule} from "@scope/library"). In some circumstances, it is desirable to prefer the sub-path specifier over the top level ("barrel") re-export. I don't see any way to do that using the current importModuleSpecifier options.

Ideally, the mode would resolve the preferred specifier, then walk up any export from statements and use the original source. If that's not possible, perhaps an MRU option could be implemented, so that if I manually pick a specifier path for a given module once, that same path is used for future auto-imports.

💻 Use Cases

I normally stick to the default "shortest" preference, which prefers the top-level re-export (if present). This makes the build tooling work harder to prove that a given module is tree-shakable, and in rare cases can lead to circular reference issues, as the load order of interdependent barrel exports becomes too convoluted to untangle automatically. Importing only the sub-module being used can avoid these problems.

Beginne damit, die Behandlung von TypeScript für auto-imports bezüglich der Option importModuleSpecifier und der bestehenden Präferenz für den kürzesten Pfad nachzuverfolgen. Vergleiche die angeforderte direct-export-Präferenz mit dem aktuellen re-export-Verhalten und ermittle anschließend, wie sie verfügbar gemacht und getestet werden sollte. Erledigt ist die Aufgabe, wenn Benutzer eine Präferenz auswählen können, die sub-path-Spezifizierer bevorzugt, ohne die bestehenden Standardwerte zu ändern.
