Dependencies Problem

[Duo-Huang]

 "peerDependencies": {
    "@babel/runtime": ">=7.11.0",
    "@codemirror/state": ">=6.0.0",
    "@codemirror/theme-one-dark": ">=6.0.0",
    "@codemirror/view": ">=6.0.0",
    "codemirror": ">=6.0.0",
    "react": ">=16.8.0",
    "react-dom": ">=16.8.0"
  },
  "dependencies": {
    "@babel/runtime": "^7.18.6",
    "@codemirror/commands": "^6.1.0",
    "@codemirror/state": "^6.1.1",
    "@codemirror/theme-one-dark": "^6.0.0",
    "@uiw/codemirror-extensions-basic-setup": "4.23.10",
    "codemirror": "^6.0.0"
  },

This is the dependency declaration I saw. I found that everything in @codemirror/view is exported in @uiw/react-codemirror, so I can use it directly without needing to install @codemirror/view myself, which is great.

But when I want to use something from @codemirror/commands, it's not exported in @uiw/react-codemirror, so I need to install @codemirror/commands myself. If the versions are inconsistent, will this cause duplicate packaging? I'm confused about why @codemirror packages need to be declared in dependencies. Can someone help explain this? Thank you.
