Allow control of the page that gets reloaded

[mehcode]

Currently on a new service worker control, location.reload() is called. Can we configure this so instead we can do location.href = "/" or the equivalent? I'd much rather have an application reload back to the "home" on an update where the user has explicitly said "yes, I want to update" from the prompt.

I also prefer to redirect to index page as the page where the update was installed could have been removed with the update.

It would be nice to have a hook function for overriding the default reload behaviour.
(Some use cases: modify location url or prevent reloading in some special situations)

I was trying to set location after updating service worker, but this resulted in strange behavior in recent Chrome versions - page was stuck at being reloaded (favicon spinning):

const updateServiceWorker = registerSW({
  immediate: true,
})

async function update() {
  await updateServiceWorker()
  window.location.replace(startUrl)
}

I guess for now better way is to use History: pushState or replaceState before updating.
