Maybe create a PR instead?

[TimTheBig]

Will do, should I leave the new lines or put them on one line?

[melroy89]

I believe they have it all on a single line.. So I would stay with that. At least the arrays are on a single line.

VSCodium is using the same extensionEnabledApiProposals as Visual Studio Code. I've checked.

Here the script doing it https://github.com/VSCodium/vscodium/blob/master/build/update_api.sh

Those Apis depend on the version of the editor and of the extension.
Your needs seem like an older version

This is the current product.json, as you can see missing quite a lot:

    "GitHub.copilot": [
      "inlineCompletionsAdditions"
    ],
    "GitHub.copilot-nightly": [
      "inlineCompletionsAdditions"
    ],
    "GitHub.copilot-chat": [
      "handleIssueUri",
      "interactive",
      "terminalDataWriteEvent",
      "terminalExecuteCommandEvent",
      "terminalSelection",
      "terminalQuickFixProvider",
      "chatParticipant",
      "chatParticipantAdditions",
      "defaultChatParticipant",
      "chatVariableResolver",
      "chatProvider",
      "mappedEditsProvider",
      "aiRelatedInformation",
      "codeActionAI",
      "findTextInFiles",
      "textSearchProvider",
      "contribSourceControlInputBoxMenu",
      "newSymbolNamesProvider",
      "findFiles2",
      "extensionsAny",
      "authLearnMore",
      "testObserver"
    ],

[TimTheBig]

Is it possible that those APIs are not experimental in VSCode?
