Hi all,As part of fixing the architecture-tests-production Connector rule in this PR [1], it appeared that (external) connectors depending on the non-public Preconditions/VisibleForTesting classes was a violation to the "connectors should not depend on non-public classes that are not in the connectors packages". I'd like to discuss making these tools public.
