This is part of a larger project, tracked in #16698, to entirely rework the rebroadcast mechanism to no longer leak sensitive information.

Most recently, Amiti has focused on increasing test coverage for the P2P layer to ensure a robust codebase. Having strong automated test coverage allows developers to make changes with confidence and is standard for software projects. With Bitcoin Core, the current system we have available for testin...
