I was imagining somethjng like this as well, but unfamiliarity with iOS made me wonder if possible.
Personally I think the issue is slightly overstated (or I'm just not popular enough and get fewer notifications) but my use pattern usually would naturally lead me to ignore such notifications by turning them off completely. Only messages get a pop-up for me on Android (or banner in iOS) and for large group chats they only get buzzes or noises.
Maybe iOS and Android can have a priority group you can set for instant delivery and then hold non priority notifications until a period of inaction from the user, adding an small delay.
But really, the occurrence rate seems pretty low to me from my workflow. And I live on my phone at work.
