Are they aware that namespaces exist? Surely you're getting more out of your clusters by having few clusters running many pods instead of many clusters running few pods?

At my job we also have some redundant clusters but that's because we're in the middle of a transition (really two transitions, the first of which was never completed), of the 10 clusters that fall under my responsibility 6 will hopefully be gone by the end of this year.
