As a long-term pycharm user that recently migrated to VSCode im quite happy to see jetbrains building this. My main gripe with their stack is that I work across many languages and workflows and I like to use the exact same keymaps configurations and so on and pycharm just didn't give you that.
I really love the idea of the virtualized file system allowing you to develop anywhere. I hope this works well. Comparably, VSCode's remote containers really do a poor job of allowing one to develop over ssh connections, which I do constantly.
