   @paul-rogers, thanks for the review!
   These plugins should be of different types to reproduce the issue, for example, JDBC and Elasticsearch, or JDBC and Cassandra, so it is a problem for adding end-to-end test since we don't have a module with several plugin dependencies.
   
   Regarding updated rules, the main change is in its constructor, now it has the `RelOptRuleOperand` that controls conventions of the rel nodes, but it is slightly problematic to create all required instances for checking whether the rule would or wouldn't match the specific rel node.
