The types change is basically because the types only exist for the ESM exports for those packages. NodeNext/Node16 resolution works for ESM but not for CJS which is maybe the issue.

The language isn't currently declared as "type": "module" though it actually should be b/c that's the bundled format. I'll make that change when we do the node version bump + service refactor.
