With Editor: Format On Save Mode set to modifications, VSCode will sequentially send requests to its rangeFormatting provider(s). It'd be nice if the whole list of ranges could be sent at once instead of sequentially, allowing the formatter to handle this batch as it sees fit. This could be achieved by modifying registerDocumentRangeFormattingEditProvider to take an additional optional metadata parameter that the provider can use to express support for this multiRange mode.
