Adaptive icons for Android is now CRITICAL (missing icon can corrupt devices!)

[BorisHansen]

As detailed here, not providing an icon for your push messages in Android Oreo will cause the app to crash in the background when a push notification is received. This can cause an endless loop and may require factory reset

Adding SDK ability to specify adaptive icons is now critical.

Also, to clarify, I'm experiencing the described crash issue with my own app after updating my test devices to Oreo, although fortunately not in a loop. According to Play Console, crash reports have increased by 6000% for my app since releasing the mandatory update where targetSDKVersion is set to 26.
