Any progress on a solution to this bug? It is still marked as 'in product plan'.
ArcMap must be removed from all USGS computers by February 2024. When that happens, there will be no arcpy method to export the spref node into CSDGM metadata. For ArcGIS Pro we have been using a workaround that uses code from the Metadata Wizard library, but the resulting XML files for some spatial references are not completely valid.
