deps(a)+deps(b)is equivalent todeps(a+b). The latter is more efficient because it doesn't have to deduplicate common dependencies between a and b. This performance issue has been triggered in our configuration, as we track roughly 700 targets and 1600 transitive dependencies in our monorepo.Running
