What's curious, is that the PR that introduces this change is the only PR on the repo that has discussion limited to collaborators only: <a href="https://github.com/dotnet/sdk/pull/22217" rel="nofollow">https://github.com/dotnet/sdk/pull/22217</a>
Editorialized headline, but it is disappointing. The feature is misnamed since it's a VS feature and not a feature for the entire .NET ecosystem (including VS Code).
