Contributor guide

Research direction
Review the referenced PR discussion #8169 to understand the replace mergeType field. Then, examine the current implementations of BackendTrafficPolicy and SecurityPolicy in the codebase to determine where to add support. Look for existing mergeType handling in other policies as a pattern.
