What origin would we use?

I am not sure the pull model here is the way to go. In order to attach to the
workers, we'll need updates to be pushed. So I think what needs to happen is
upon "enable", all the registrations (or service workers) are sent to the
front-end along with their metainfo. Something like
workerRegistrationUpdated(registration). Then, as they change, updates will be
issued. Wdyt?

Ah yes, I agree with you.

I changed to push model.
