One issue is that things don't stay DND or blocked. All the apps update individually, and also every few months the vendor publishes a new OS update with yet more enshittification to turn off (where you even can! Search for how to turn off "at a glance" to see a tide of consumer misery and frustration. The vendor has important awesome things they want to do with your device, and only occasionally do those happen to align with the boring unimportant everyday activities /you/ want to use your device for.)
I would pay serious money for an ecosystem that promised no enshittification creep, but sadly that is not on the cards.
Huh, strange, is this specific to Android? Because my DND mode stays DND throughout updates, except for the contacts and apps I've already marked as the exceptions. I don't think I've ever had the problem of unwanted notifications.
