    - [x] wait for new version of rollup-plugin-vue,
      https://github.com/vuejs/rollup-plugin-vue/issues/408
  - tusimple theme
  - [x] clean delegate
  - [x] site production tag (bug)

  - [x] remove hollowoutable
  - [x] styleScheme, css variables 组件
    - 文档之后再说
  - [x] use-global-style ? 感觉效果不会特别好而且还是很无谓的性能开销
    这个问题可以之后再思考，现阶段 vue 的写法还是全局 install
  - [x] dynamic-input, no value

  - [x] test rollup treeshaking
  - [x] test webpack treeshaking
  - [x] menu utils render
  - [x] dialog bug
  - [x] data-table css vars
  - [x] typography css vars
  - [x] spin css vars
  - [x] radio css vars
  - [x] checkbox css vars
  - [x] avatar css vars

  - [x] vue 在 $attrs 的处理上 dev 和 prod 还是有差别 https://github.com/vuejs/vue-next/issues/2741
