The Extract Data Wizard available in the Distributed Database toolbar in ArcGIS Desktop (shown below) has not been recreated in ArcGIS Pro.
This wizard provides a very simple, clean method of putting data with all relevant domains, subtypes and relationships into a new file GDB (I do not have any experience with XML). And, users have the option of choosing Schema Only, which creates a clean shell of the feature class(es) selected. No ZIP files, no packages, no XML imports/exports... no fuss! This is extremely useful for documentation, testing, etc. Please consider adding this essential function to ArcGIS Pro. Thanks.
