This parameter was added to avoid sending a slew of empty diagnostics for the initial workspace load. It's actually not needed anymore, as we can just detect if we have previously sent diagnostics for the given file, and if not we shouldn't send an empty diagnostic. This is true for all cases, not just the initial workspace load.
