To be honest, how Cloudflare Workers work is a bit of a mystery to me as I've only done some very basic prototyping with the service (and not really focusing on the "edge" aspect of them), but it seems like the important "stuff" that makes them what they are is how they are deployed.
I am REALLY going to show my ignorance here, but is there some chance that the idea is these "workers" are intended to be deployed in the users browser for example, as actual service workers or something? i.e. is this more of a framework for creating service workers vs running in the "backend"?
