The main issue is they often try to write code using dated/unsupported packages, but simply asking them not to use any out of date components or units will give you a baseline to do most things or from first principles.

Gemini 2.5 was the last one I used for generating an interface to a really old OLE based SCADA system, the base code it generated required almost no re-work to read and write the interface.
