ArcGIS Pro contextual help notes that "Tools that honor Output CONFIG Keyword environment will use the specified keyword when creating datasets in a geodatabase."
My idea is that "Tools that honor Output CONFIG Keyword environment can provide the user with a drop-down list of keywords that are available in the target geodatabase."
Example: Geoprocessing > Copy > Environments > Output CONFIG keyword > blank field with no dropdown list.
Available keywords in my example target geodatabase are:
DATA_DICTIONARY
DEFAULTS
GEOGRAPHY
GEOMETRY
IMS_GAZETTEER
LOGFILE_DEFAULTS
NETWORK_DEFAULTS
