I think we should:

• Revisit all internal usages of notifications and consider if they should be converted to modal dialogs if they require immediate user actions
• Once we figure out the best thing to do in VS Code core we should update our extension guidelines so extension can follow the patterns that we do in core

Ideally this exercise would move "important" to be modal dialogs, and thus we can start exercising a more aggressive hide strategy towards regular notifications.
