Thanks for the contribution! However, we currently do not have any reported issues in the repo related to CS1705 version conflicts, and this is not a commonly encountered error in our context. Expanding the contributing guide with this information might lead to confusion rather than providing value. Given this, I don't think we should include this update. I’ll be closing this PR for now. Feel free to reopen if there’s a strong case based on actual occurrences in our repo.
