The A/B test infrastructure is. It’s easy to wire up experiments because there is always a template/recipe to do so. Multiple subsystems can be strung together (eg: Experiment arm XX in subsystem A triggers Experiment arm YY in subsystem B). Analysis is simplified too since all the core metrics are already in place and ready for analysis.
