lmao, I've turned off notifications from literally every app except banking ones.
If you are afraid of losing out on important ones, there is feature atleast in Android to only turn off notification categories. Although this depends on app and sometimes they don't expose proper category names.
I used to do that but then I realised if it's important enough information there would be redundancy to it.
I've sometimes missed notification from swiggy where they ask you to edit cart because item is not available but it happens rarely(also they call you if you didn't respond to notification) and I'm ok with that because the alternative is getting these shitty notification daily. So inconvenient experience once a month is better than everyday
Unfortunately app notifications are abused so much that eventually we will all turn if off similar to SMS
