Interesting! I built something similar — Echobell (https://echobell.one https://echobell.one). Beyond push notifications, it also supports actual phone call alerts, which is useful when you really can't miss something (e.g., server down at 3am). Also has email-to-notification and channel sharing for teams. Worth a look if you need that extra layer.
