The native apps for my phone aren't really reliable enough at letting me know about delays or gate changes, I don't expect a web push notification to be any better at something that's already untrustworthy, especially on a system that lacks a cellular modem to stay online all the time. Even if they did work perfectly and could be trusted to serve that purpose, no company would only send status updates about your flight in the long term, they're unable to restrain themselves and will view it as an advertising avenue just like they do with phone apps.
