Correct way of extending tsconfig lib in a vue project

[Der-Alex]

My question is kind of related to this topic: https://github.com/orgs/vuejs/discussions/13583
On a fresh vue installation with typescript, a tsconfig.app.json will be created, that extends https://github.com/vuejs/tsconfig/blob/main/tsconfig.dom.json.
The tsconfig.dom.json says:

  // Target ES2020 to align with Vite.
  // <https://vite.dev/config/build-options.html#build-target>
  // Support for newer versions of language built-ins are
  // left for the users to include, because that would require:
  //   - either the project doesn't need to support older versions of browsers;
  //   - or the project has properly included the necessary polyfills.

So Baseline availabe features like Object.groupBy are unknown to typescript.
As far as I understand, I would have to add my own libs to the tsconfig.app.json:

{
  "compilerOptions": {
    "lib": [      
      "ESNext", // Or whatever I need
      "DOM",    // I have to set all the other values, because I override lib here
      "DOM.Iterable"
    ],
  }
}

To me this feels kind of wrong, because as soon as the tsconfig.dom.json changes in a future update, my lib configuration could override lib configurations from tsconfig.dom.json that I don't know about.

So is this the correct way to deal with making new features available? Or is there some smarter way that I don't know?
