There already is a standard though for sending messages, that doesn't consume much and can interleave multiple payloads, it is XMPP and is specified by the IETF. In fact FCM allowed XMPP at some point. I'd agree with you that XMPP should replace all those reinventions and both Google and Apple should use it, but alas.

It totally makes sense to use UnifiedPush instead of websocket though, because websockets are a hack because using HTTP here is silly, and it requires specific machinery. It's easier to rely on another party. Deltachat isn't the same: there is something that works natively, that should be the preferred way of doing notifs
