@Rich-Harris mentioned this already in #2 (comment) that named imports/exports are really difficult or even completely unfeasible.

The problem is that the current pattern is extremely popular, and established tools (even rollup) work well with it.

So far I use rollup with external to link to npm modules and it works like expected with named imports. Switching to rollup-plugin-commonjs however breaks because it now complains about missing exports (since the converted modules only have a default export and nothing else).
