The user legitimately considers the application as hostile - hence sandboxing... Notification spam filtering is now the obvious need at the sandbox's edge, with the whole customizable arsenal we have come to expect for our inbound mail. Of course, Google will not cooperate with anything likely to reduce sacro-sanct engagement !

I definitely run all my emails through an LLM filter and wish I could do the same for push notifications!

Except that they did. Android has notification channels. Now, I suppose we could argue that Google could be more ham-fisted about forcing apps to use them, but that's murky.

In fact, Uber on Android does use these notification channels. I just have "All Promotions & Recommendation notifications" disabled, and then "Taking a ride" channel enabled.
