Not if the OS manages the batching of those updates. Then it's barely any more hostile than what the OS needs to do to manage things like receive phone calls.

I think you're also strongly in the minority on this. People who use messaging apps prefer the ability to get notified (at least sometimes) when they get a message, even an unexpected one. That true for phone calls, texts, emails, or Whatsapp/signal/fbm etc.

Message notification is not impacted here. You don't need to open the full app for that to happen.

If the app uses encrypted messages, you just have to write an extension to handle the decryption on device while the app is not running.

If the user wants to interact further after reading the message notification, they open the full app.
