Hi, given the Dart VS Code extension supports suggesting VS Code extensions based on the installed packages, it would be great to either remove the allow list or have a clear process of how a new extension can be added there.

For DCM, we have a presets package https://github.com/CQLabs/dart-code-metrics-presets that clearly indicates that the project uses DCM and therefore the user would benefit from such a notification if the DCM extension is not installed.

Also, if the required configuration is not documented anywhere, it would be great to have documentation for it as well.
