Support Web Push Channel Aggregation

[vibgy]

Services use pub-sub topics to deliver one-to-many push messages. Wondering if pub-sub topics can be implemented with web-push?

Autopush doesn't support it yet (mozilla-services/autopush#643), I don't know if FCM supports it.

Sorry, I think you meant https://martinthomson.github.io/webpush-aggregate/. It isn't implemented by anyone yet.

That webpush-aggragate doc is super old "Expires: April 11, 2015". Topic support isn't an easy task because a single topic message would need to be encrypted for every single topic subscriber.

Best bet would for a library to implement topic utilising this library to perform the encryption and sending.
