It would help if there were a geoprocessing tool for creating and managing entries in Oracle's user_sdo_geom_metadata table/view.
I find it clunky to manually create those records through SQL. Every once and a while I make a mistake when writing the SQL, and it ends up being a headache. I'd be less likely to make a mistake if I used an OOTB GP tool.
Also, an OOTB tool would be more convenient for deleting entries.
