That is documentation for Google Cloud Messaging, not WebPush. Under
WebPush, topic collapsing is purely an appserver option when sending a
message such that if a message of the same topic was already stored,
the new message will replace it.

As far as I know, there are no implementations of Webpush topics yet,
the spec describes it here:
https://tools.ietf.org/html/draft-ietf-webpush-protocol-04#section-6.4

We're probably a few weeks or month or so out from implementing this
for Firefox.

Cheers,
Ben
