Research direction
Start with the targets section in father’s config documentation and inspect how rc-util’s build currently applies the default IE11 target. Compare a modern-browser target such as Chrome 86 with the current output, including the minified and gzipped bundle size. Done means the target choice is defined and the reported bundle-size reduction is verified without changing the intended build behavior.

Description
根据 father 的文档 https://github.com/umijs/father/blob/master/docs/config.md#targets 使用 babel 构建默认兼容 ie11，导致产物体积偏大（尤其是 @babel/runtime 引入的很多）。而 antd 5 是不支持 ie 的，这些 polyfill 就显得不是很必要。是否可以考虑将 targets 改为 { chrome: 86 } 之类的现代浏览器配置？
经过我的测试，可以将 rc-util 的 bundle 体积从 2.8kB 减少到 1.7kB (minified + gzipped)
