Research direction
The issue names BroadcastNestedLoopJoin and a plan rewrite but provides no file or test references. Start by locating the existing BroadcastNestedLoopJoin handling and related join-plan rewrites, then determine what full outer support requires. Done means full outer BroadcastNestedLoopJoin plans are supported and covered by the relevant tests.
