Personally I wish they’d never been invented, I don’t let any apps send me notifications other than chat apps and even then with no sound and all group chats are muted permanently. I can’t stand the constant ping of apps trying to get you to engage with them, I want to engage on my schedule not anyone else’s especially some Silicon Valley product manager’s. Even in this much quieter state not having my phone feels exactly like not having my baccy felt when I used to smoke, until I got into the Fediverse I was tempted to pull the plaster off entirely and throw it in the sea.
I’m also a bitter and cynical software engineer who should under no circumstances be consulted for UX advice, so it’s probably wise for Lemmy to implement them.
