Is there a way to batch export metadata as FGDC formatted xml in ArcPro? In ArcCatalog there was a geoprocessing tool called Export Metadata Multiple that would allow you to export every metadata file for a geodatabase, but I see no similar functionality in Pro to batch export.

---------
Export Metadata Multiple and Validate Metadata Multiple
The Export Metadata Multiple and Validate Metadata Multiple tools were provided to support buttons on the ArcCatalog Metadata toolbar. These capabilities are supported in ArcGIS Pro without the need for these tools.
In an ArcGIS Pro Python script, you can export (and in the future validate) metadata for many items by accessing datasets and files using the arcpy list functions, and accessing maps and layers using the arcpy.mp list functions. Use the appropriate Metadata class method to manage metadata for the items returned by those lists.

So it sounds like scripting is way forward

and the mapping module and associated arcpy links in the table of contents of the Python section of the help.
Too bad, wish it was a tool, but thanks!
