> In CALCITE-3781, calcite can specify a hint for a relNode to let the planner exclude some rule when optimze. But as [~julianhyde] said, 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.
