> In the https://issues.apache.org/jira/browse/CALCITE-3781, calcite can
> specify a hint for a relNode to let the planner exclude some rule when
> optimze. But as [~julianhyde] sail, it's strange to only check for the
> {{rels[0]}}. If we have a rule to push a common project to the source scan,
> we want to prevent the common project optimized from the ProjectMerge Rule,
> it can not work, as the preserved one is at the bottom.
> So I proposal to check all the rels for the rule.
