Why does nobody talk about how jellyfish blooms are actually a sign of ocean health?

Last weekend, I was at the coast with my kids and we saw a massive jellyfish bloom. It got me thinking - everyone says it's a sign of overfishing or pollution, but what if it's the ocean's way of rebalancing itself? I read a study that some jellyfish species indicate robust plankton populations, which are VITAL for the food web. Maybe we're too quick to judge these gelatinous creatures as pests.
