Can someone explain what the service worker strategy accomplishes that plain old http Cache headers don't? It saves a (almost zero weight) network roundtrip, but feels like it's re-inventing the entire wheel for that small (I think) optimization? Am I missing something?

that they can be used to compute stuff locally

I imagine ideally we want user choice of where the computation is happening. if on a mobile device I'd save battery in exchange for network latency

but in a desktop computer I'd rather do as most local computation as I can

For the sort of thing that are fast enough that network latency is relevant, on a mobile device you save battery by doing them locally. The radio takes more power than the cpu.
