The transpilePackage affordance provided by Next.js only kicks in when we import
our TypeScript packages into the apps. But when importing them into another
(internal) package within our monorepo, the transpilation doesn't happen, so
VSCode (rightfully) complains.
It works out fine at runtime (since the actual app code will transpile it
correctly), but this is not a good DX, and smells hacky. So for now, we avoid
our dependence on the export map by keeping the hierarchy rooted at root.
