现象：

期望像 webapck 一样：

demo 中只是用 antd 举例，实际使用中依赖的三方包导出不规范， 如果使用 babel-import-plugin ，需要定义不同的customName

Reproduce Steps

pnpm dev

webpack默认也不会实现该功能，如果需要的话试试这个 https://www.rspack.dev/config/builtins.html#builtinspluginimport

我用cra建的项目默认是支持这个功能的，就是上面第二张图，没有做任何额外的配置。builtins.import 现在无法满足我的诉求，因为需要定义不同的customName

我没有在cra的文档上找到支持该功能，请提供可复现的cra的demo

经确认，这个其实是webpack的一个treeshaking优化，当手动配置 antd的package.json的sideEffects:true的时候，导入路径就变成了antd/lib/index.js，后续我们跟进下这个treeshaking优化， cc @IWANABETHATGUY

just a gentle nudge, @IWANABETHATGUY @hardfist on this bug for an approx ETA .
It is a major blocker for my experiment to transition to rspack and it would help me re-prioritise mu tasks.
