Thanks for sharing this SEP. Yeah some system notifications will go away, but servers will still be able to send custom notifications. Those can be turned into push notification on the device of the user or even actions that the user's device can do programmatically.

Actually, after reading more carefully, it seems that custom notifications won't be supported anymore in favor of the `subscriptions/listen` RPC endpoint. Maybe the upcoming extensions will make it possible?
