I think it will cost the same to evaluate all of them, might as well prune as many as we can? It will lead to less rebuilds. Otherwise if we have rgs 1, 2, 3, 4 and after 1 we could skip 2 and 4 but not 3 we will do 2 rebuilds instead of 1. Good catch @adriangb ! -- This is an automated message from the Apache Git Service.
