I would argue there's definitely bad implementations of toast notifications. On iOS I wish I could have more control over them to where I can almost automate them, I have notifications that if I haven't looked at it in like 12 hours, just remove it. It is also too easy to dismiss them, and never get them back. I want a "History" panel somewhere, so I can recover accidental dismissals, maybe let it live for 24 hours before it wipes forever. Sometimes I get a notification I'm interested in and dismiss by mistake, from an app I can't remember, or somewhere impossible to find within the app (I'm looking at you Nextdoor). App devs, if you're going to send me a push notification, please archive them within your app if the OS wont.
