To clarify, the chunk splitting is causing issues in my application because it causes TypeScript to include import(somePath).SomeType statements in my .d.ts files when I export a type that's coming from a tsup-built library. But somePath is a TSUP's dynamically generated chunk file, and so not covered by my package.json's "exports" field, and thus not resolvable. My workaround was to add "./*": "./dist/*", in my package.json's exports, but that pretty much defeats the isolation benefits of the "exports" field
