I would like to be able to use a database connection to get workspace properties from Describe. Using Pro 3.1.3, accessing any of the workspace properties everything results in
OSError: "CIMDATA=<CIMStandardDataConnection xsi:type=...rest of connection string" does not exist
If I'm building paths to layers and tables in a script, I sometimes use Describe to get workspace information from one layer to build another. It's also helpful in debugging.
Here's a question discussion for reference.
