For two reasons:
* If the page does some initialization asynchronously then it might
miss that the "deregister" event fires. I.e. it is very easy to
accidentally register the onderegister event handler "too late".
* It would require that we for each page that the user visits check if
that page has a registration, and if that registration has been lost
by the server. We only want to do this on pages that care about push
registration and is actually going to make a registration if needed.
Not for every page the user visits.
