he proposed resolution suggests modifying the TermManager->migrateReference() method to check for duplicates and handle them accordingly.
Before implementing such a change, there are a few considerations and steps you may want to take:
Impact Analysis:
Understand the current use cases and scenarios where merging terms might occur.
Identify potential negative side effects of preventing reference duplicates. It's essential to consider various content types, taxonomies, and use cases within the Drupal instance.
Community Discussion:
Discuss your proposed resolution on Drupal forums or community channels to gather feedback from other developers and site administrators.
Check if others have faced similar issues or if there are alternative solutions that have been proposed.
Backward Compatibility:
Ensure that the proposed changes do not break backward compatibility with existing modules, themes, or custom code.
If the change is significant, consider providing migration paths or tools for existing installations.
Configuration vs. Default Behavior:
Determine whether the duplicate prevention should be a default behavior or configurable. Some site administrators may have specific use cases where allowing duplicates is acceptable.
Documentation:
Update documentation to reflect the changes, explaining the new behavior and any configuration options.
Provide clear guidelines on how site administrators can manage term merging and avoid potential issues.
Testing:
Implement thorough testing to ensure the changes work as expected in various scenarios.
Test with different Drupal configurations, including diverse taxonomies and content types.
Security Considerations:
Evaluate the security implications of the proposed changes.
Ensure that the modifications do not introduce vulnerabilities or security risks.
Drupal Core Contribution:
If the changes are deemed beneficial and well-received by the community, consider contributing them to the Drupal core.
Remember that any changes to core functionality should be approached with caution, and thorough testing and community input are crucial to ensuring a robust and widely accepted solution. I did same things for a blog that was covering tesla car charging topic on his.
