I think this can be fixed more generally by biasing towards newer data in model outputs and putting more weight on authoritative sources rather than treating all data the same. So no one needs to go in and specifically single out Go code but will instead look at new examples which use features like generics from sources like Google who would follow best/better practices than the rest of the codebase.

I know Claude will read through code from Go libraries it has imported to ensure it is doing things correctly, but I do have to wonder for other languages and those small libraries, if we'll start seeing things like AGENT_README.md a file that describes the project, then describes what functionality is where in the code, and if necessary drills on a source file by source file basis (unless it's too massive - context limits are still limits). In any regard, I could see that becoming more common. Especially if you link to said file from the README.md for the model to go to. ;)
In Stackoverflow data is trivial to edit and the org (previously, at least) was open to requests from maintainers to update accepted answers to provide more correct information. Editing is trivial and cheap to carry out for a database - for a model editing is possible (less easy but do-able), expensive and a potential risk to the model owner.
