We ran only two (very small) clusters for some time in the past and even then it introduced some unnecessary overhead on the ops side and some headaches on the dev side. Maybe they were just growing pains, but if I have to run Kubernetes again I will definitely opt for a single large cluster.
After all Kubernetes provides all the primitives you need to enforce separation. You wouldn't create separate VMWare production and test clusters either unless you have a good reason.
