Thank you for opening the PR and thank you for the analysis. Can you add a fragment describing the fix in https://github.com/pylint-dev/pylint/tree/main/doc/whatsnew/fragments, please ?

Also I suppose you used dict.fromkeys for performance reasons compared to sorted or something else ?

Will do.
Also I suppose you used dict.fromkeys for performance reasons compared to sorted or something else ?
The intent was to avoid duplication of paths as the previous code did and also have a deterministic order. After this change, whether or not we see the error I mentioned in the issue will depend on the order of file and modules specified in the command line.
