Embedding C# sources in PDB with new csproj

Question

The recently-released .NET tooling seem to have support for embedding C# in PDBs, which should improve the experience of stepping into third-party, etc. Running csc /?

    netstandard2.0
    true
    [...]

From what I observed locally, it behaves the same as the mentioned EmbedFiles target.
