The reason Node disallows this has nothing to do with TypeScript being owned by Microsoft, it's because there's no guarantee the TSConfig settings used in the library you're pulling in match the ones in your project. A mismatch would mean you would get type errors inside the library code (assuming you're doing some form of type-checking in your application, otherwise what's the point of even using TypeScript).

The TypeScript compiler itself comes with everything you need for this. See: https://www.typescriptlang.org/tsconfig/#declaration

There are other advantages to bundling, but it's not strictly necessary if all you care about is publishing TS on NPM. Declaration files solve the problem by supplying the resolved types of the publicly exposed identifiers. Also has the added advantage of not locking out plain JS consumers.
