@karthiknadig currently we have "Format Notebook" command in the core and also notebook format on save. If users have black extensions installed, it works as expected. May I ask if this would change how we run formatters from the core?

From what I can tell, it should not. The LSP server registers itself as a server that can handle notebooks. When I have a prototype ready, we can look at how LSP client handles notebook mode registration.
